The Kid At The Back: Sol Route, Yandere Secrets & Complete Ending Guide

In the psychological visual novel The Kid At The Back, Solivan "Sol" Brugmansia stands as one of the two main romanceable characters, serving as the absolute narrative polar opposite to the polite class representative, Crowe. Initially presented as a shy, quiet, and easily overlooked student who always hides in the back row of the classroom, Sol quickly reveals a much darker side.

Beneath his introverted and submissive exterior lies an aggressively possessive, stalker-style yandere who will stop at nothing to claim the player. From break-ins and midnight spying to severe chemical subdual and brutal physical violence, Sol represents a deeply dangerous yet irresistibly captivating romantic path. This comprehensive guide covers his full character profile, decrypted deep lore, precise route choices, and a step-by-step ending guide to help you survive his obsession.

Visual Aesthetics

Sol is exceptionally tall, possessing a lean build that stands out in any room. He has shoulder-length black hair styled in a half-up, half-down look, accented by deep green and muted olive streaks. His bangs are split into three distinct sections, with a long central strand framing his face, topped by two small cowlicks on his crown. His eyes are narrow and sharp, featuring a striking case of central heterochromia with an orange inner ring and a deep red outer ring.

His wardrobe is heavily defined by dark colors and alternative fashion. He typically wears a black-and-green striped long-sleeve shirt underneath a loose, brownish-black graphic t-shirt, paired with deep green jeans. A lime-colored metal chain hangs from his left hip. He accessorizes heavily, wearing a black-and-green buckled choker and a long silver necklace with a two-pronged key pendant.

Body Modifications and Markings:

• Left Ear Piercings: Three lobe piercings (one large, two small) paired with two upper cartilage hoop rings.

• Right Ear Piercings: One large, distinctive inverted crucifix earring alongside two smaller lobe studs.

• Facial Piercings: A classic "spiderbite" piercing on the right side of his bottom lip, holding two black metal hoops.

• Bandage Variants: Sol frequently appears with heavy medical dressings, including a fully bandaged left hand and facial gauze. These visual cues shift depending on off-screen altercations with campus bullies.

Deep Lore & Backstory

While regular students at Olympieus University simply view Sol as a creepy or eccentric loner, digging deeper into his history reveals a life shaped by isolation, harassment, and an obsession years in the making.

The Toxicity of the Angel's Trumpet

Sol’s surname, Brugmansia, is a deliberate and chilling piece of narrative symbolism chosen by the author. In botany, Brugmansia is the scientific name for the "Angel's Trumpet"—a plant that produces stunning, sweet-smelling bell flowers that are highly toxic and potentially lethal. This perfectly encapsulates Sol's entire character arc: a sweet, vulnerable, and deeply devoted romantic partner on the surface, masking a fatal, poisonous underbelly.

Years of Silent Stalking

A shocking revelation comes to light during his confrontation scenes. Although the player barely notices Sol on the first day of university, Sol has actually been secretly infatuated with the player for years. According to school rumors and admissions from campus bullies, Sol's obsession predates college entirely. He has spent years watching the player from afar, cataloging their habits, tracking their movements, and waiting for the perfect moment to force his way into their life.

Meta-Lore: The Fourth Wall Name Break

Sol possesses an uncanny, eerie awareness that manifests if the player attempts to manipulate the game’s naming systems. During the initial character creation, if you attempt to set your own character's surname to "Brugmansia", Sol completely breaks the fourth wall.

He laughs nervously, his expression shifting as he directly addresses the screen:

"I... Haha... In a hurry aren't we? I'd love to share the same last name with you... But I need you to remember."

This implies that Sol's obsession transcends the linear progression of the game's timeline, viewing the player as a prize he is destined to own across any version of reality.

Walkthrough & Dialogue Guide

Navigating Sol’s route requires a careful understanding of his triggers. To successfully unlock his content, players must learn when to yield to his stubbornness and when to indulge his dark curiosity.

Day 1 Walkthrough Choices

The Library Seat Confrontation

Upon entering the campus library, you find Sol stubbornly occupying your favorite study desk:

• Show curiosity and investigate his hand: This path triggers a deeply intimate moment where Sol notices your gaze. It rewards a massive affection boost and unlocks deeper dialogue regarding his recent physical altercations.

• Demand the seat back or remain hostile: This causes Sol to retreat into a cold, expressionless silence, temporarily locking you out of his immediate Day 1 soft interactions.

The Author's Puzzle Shortcut

If you encounter the cryptic riddle event in the library and choose to entirely give up on solving it, Sol will sigh softly and provide the absolute answer himself:

• He reveals the solution is "Sarah Anna Lewis", quietly adding that she was "someone that the Author had close relations to." This subtle hint serves as a major piece of meta-narrative lore regarding the game's creation.

The Evening Courtyard Crisis

If you stay late on campus, you will witness Sol getting cornered by a group of red-haired bullies.

• Intervene and defend him: Sol is deeply moved by your protection, setting his attachment level to a dangerous threshold.

• Watch from the shadows: You will witness Sol's submissive persona slip away as he fiercely retaliates with unexpected, raw physical violence once he believes he is unobserved.

Day 2 Walkthrough Choices

The Campus Escape Option

When class becomes unbearable, Sol and his fiercely loyal companion, Hyugo, will offer you a chance to ditch the university gates entirely:

• Agree to skip class with them: This is the absolute mandatory trigger required to lock yourself onto Sol’s true narrative branch.

• Refuse and stay with Crowe: This permanently derails Sol's romantic progression for the rest of Day 2, keeping you on the standard school track.

Choosing Your Destination

Once you escape campus, you must choose where the trio hangs out. Each location shifts Sol's behavior dramatically:

• The Arcade: A lighter, highly interactive path. Sol shows a surprisingly competitive, artistic side while playing games, raising his affection points to their maximum potential.

• The Movie Theater: A much darker setting. Sitting together in the back row of a pitch-black theater allows Sol’s possessive nature to take over, resulting in unsettling physical proximity and tense, whispered dialogue in the shadows.

The Rooftop Vulnerability

During a quiet moment on the school roof, Sol will drop his guard and discuss his profound loneliness:

• Comfort him and validate his feelings: This satisfies his intense craving for your undivided attention, allowing you to bypass immediate bad ends later in the evening.

• Remain silent or look away: Sol’s demeanor immediately hardens, and he begins to realize that normal romantic pursuit may not be enough to keep you by his side.

How to Unlock All Endings

Sol’s storyline features some of the most dramatic, high-stakes conclusions in the entire visual novel, heavily dictating whether you end up as his partner or his permanent captive.

The Famous "Orange Juice" Ending

This is the most notorious cliffhanger path in the community, representing Sol's full transformation into an active predator.

• Trigger Criteria: You must accumulate more than 8 affection points with Sol on Day 1, choose to skip class to the arcade on Day 2, and explicitly request that Sol walks you home to your apartment at the end of the day.

• The Narrative Outcome: Upon entering your home, Sol offers to pour you a glass of orange juice. Unbeknownst to the player, he has heavily spiked the drink with powerful sleeping sedatives. As your vision begins to blur and the screen fades to black, Sol’s gentle voice turns terrifyingly sweet. He confesses that he has been illegally breaking into your room to watch you sleep for years, concluding the demo with your character completely trapped under his absolute control.

The Day 2 Romance Climax

A highly coveted branch that rewards players who successfully balance Sol's emotional needs.

• Trigger Criteria: You must successfully trigger the Bathroom Rescue event, choose to comfort him during his emotional breakdown, and avoid raising Crowe's affection parameters.

• The Narrative Outcome: This successfully bypasses the immediate sedative trap, unlocking a sequence of deeply intimate, romance-focused scenes. Sol completely opens his heart to you, officially declaring you as his "one and only soulmate" and granting a glimpse into a fiercely loyal, albeit deeply protective, domestic life together.

Bad Ending: "No Witnesses"

This ending highlights the fatal consequences of triggering Sol’s lethal jealousy.

• Trigger Criteria: On Day 1, during the evening park encounter with Crowe, you must explicitly choose to "Kiss Crowe".

• The Narrative Outcome: Driven into a state of psychotic, possessive rage after witnessing the romantic display, Sol takes immediate, lethal action. On Day 2, Crowe mysteriously vanishes from school. When you go searching through the isolated, abandoned corners of the campus backyard, you run directly into Sol. It is tragically revealed that Sol has brutally murdered Crowe to eliminate the primary obstacle between you two, ensuring there are absolutely "no witnesses" left to contest his claim over your life.

Complete CG Gallery & Scene Deck Unlock Guide

Achieving a 100% completion rate in Sol's visual album requires precise choices across multiple conflicting playthroughs.

• The Defiant Back-Bencher: Automatically unlocked during your very first library encounter when Sol refuses to move from your study desk.

• The Crimson Stare: Unlocked in the library by choosing to closely inspect the fresh, open wounds on Sol’s palm, triggering a scene where he expressionlessly licks the injury.

• Arcade Competition Reflection: Unlocked by successfully choosing the Day 2 skipping class option and traveling specifically to the local arcade center.

• The Back-Row Shadow: Unlocked by choosing to go to the movie theater with Sol and Hyugo, triggering an illustration of Sol watching your face instead of the screen.

• The Spiked Beverage: Unlocked by successfully fulfilling all requirements for the Orange Juice path, showing Sol smiling softly as he hands you the laced drink.

• Midnight Guardian Stalking Perspective: Unlocked during the climax of the Orange Juice ending, featuring a terrifying first-person perspective of Sol standing over your bed in total darkness.

• The Backyard Truth: Unlocked by triggering the "No Witnesses" bad end, showing Sol standing in the campus shadows following his lethal confrontation with Crowe.

Character Relationships

Sol’s social circle is exceptionally small, as he views almost every external human being as a annoying distraction or a direct threat to his romantic goals.

• The Player: The absolute center of Sol's universe. He views the player not just as a romantic crush, but as his literal "soulmate" and salvation. His entire life is engineered around gaining your validation, and he experiences acute physical and psychological distress whenever you ignore him.

• Jericho "Crowe" Ichabod: Sol’s ultimate rival. Despite Crowe's outward attempts to maintain a polite, structured campus environment, Sol harbors an intense, deep-seated hatred for the class representative. Sol openly despises the hostile, suspicious glares that Crowe throws at him, and will immediately resort to murder if Crowe attempts to claim the player's affection.

• Hyugo: Sol’s closest campus companion. Hyugo acts as a buffer for Sol, constantly explaining to other students that Sol's scary, expressionless face is just a misunderstanding and that he is "good at heart." However, Hyugo’s loyalty is deeply enabling; during the Day 2 escape, Hyugo actively serves as an accomplice, helping Sol isolate you from the rest of the student body.

Trivia & Hidden Dialogue Details

• The Bandage Script Secrets: Deep inspection of the game's visual asset library reveals dozens of specific sprite configurations designated for Sol's face and hands. These files track his shifting facial trauma and gauze layouts, illustrating that his life outside of school hours is incredibly violent and chaotic.

• Unedited Obsession Text: During the dramatic climax of his Day 1 route split, the game's text engine utilizes custom red font formatting to display Sol's raw, unhinged internal thoughts. When his soft-spoken facade completely fails, his true desires flood the screen:

"Every... Waking... Day. If only you know how much I crave your attention every day... It hurts... So please... Let me... Those filthy scums think they could touch you... You're mine, no one else."
