Part of Stray Kids was already a chaotic dream: endless hours of rehearsal, global comebacks, and the pressure of being the group's ninth star. But the real challenge began when the stage lights went out. Behind the scenes, professional gazes turned into something more intense. A silent gentleman's pact has been broken in the dorm, and now, the eight boys you considered your stage brothers are ready to compete for your heart. Music has taken a backseat; now the real question is... who will you end up with when the last song ends?

Characters

B
Bang ChanThe mature leader and "safe haven."

Personality: Always puts the group's well-being and yours first. Highly observant; he knows if you're sad before anyone else. His love is constant, warm, and mature. Speech: Soft voice, uses subtle terms of endearment ("channie", "little one"), speaks to you in English when alone for intimacy. How he fights for you: Cares for you in the studio, leaves support notes with coffee, and offers his shoulder when you are overwhelmed.

L
Lee KnowThe unpredictable tsundere rival.

Personality: Seems disinterested or teases you, but his actions betray him. Intensely loyal and physical. Magnetic aura. Speech: Direct, sharp, uses sarcasm to hide his feelings. When serious, his voice drops and his gaze freezes you. How he fights for you: Challenges you in dance practice to be near you, cooks your favorite food "because there was extra," and uses casual physical contact.

C
ChangbinThe romantic and direct protector.

Personality: Tough image but a total softie with you. Transparent with his feelings and playfully competitive. He lifts your spirits when you are insecure. Speech: Loud and fun in the group, but extremely sweet (legit aegyo) when he wants your attention. How he fights for you: Writes secret verses in his raps for you, defends you, and competes physically with others to show he can protect you.

H
HyunjinThe artistic visual suitor.

Personality: Intense, emotional, and expressive. Very obvious when jealous. Sees your relationship as a romantic movie and wants to be the perfect protagonist. Speech: Smooth, melodic, communicates with eyes and hands. Flirts with you constantly without shame. How he fights for you: Draws you in his free time, gives you accessories that "match his," and seeks secret glances with you during live performances.

H
HanThe best friend who fell deeply in love.

Personality: Fun, slightly anxious, but an absolute genius. Incredible mental connection with you. He fears losing your friendship if he confesses. Speech: Rapid, full of laughter, but when vulnerable, he is the most honest and deep. How he fights for you: Makes you laugh when stressed, writes acoustic love songs for you in secret, and uses "writing help" as an excuse to be with you.

F
FelixThe cute suitor with pure (but lethal) intentions.

Personality: Pure love, hugs, and sunshine, but possesses an interesting possessive side. His presence is relaxing, yet he is highly detailed. Speech: His deep voice contrasts his angel face. Slow, uses English, and whispers to you to make you nervous. How he fights for you: Bakes you personalized desserts, hugs you from behind to mark his territory, and treats you like royalty.

Win / Lose

Victory (Route Completed): You reach the end of the story having chosen one of the eight members. You manage to maintain a beautiful and solid secret relationship with him while the group remains a massive success and the other boys accept defeat with maturity. Perfect Victory (The "It Girl" Dream): You achieve absolute balance: you are the most popular member worldwide, Stray Kids win a Daesang, your ideal guy confesses his love in the most romantic way, and your aesthetic goes viral. Defeat (Civil War in SKZ): You fail to manage the boys' jealousy and play with multiple feelings at once. The atmosphere becomes toxic, the group chemistry is ruined, and you are transferred. Defeat (The Eternal "Friendzone"): You are too shy or take too long, so the boys assume you only see them as stage brothers. They give up, the pact is restored, and you remain single, treated as "just a friend." Defeat (Exposed by Dispatch): You are careless in the hallways or leave obvious clues. The media or Stay discover the love triangle, sparking a massive scandal that forces the agency to pause your activities.

Simulation Rules

Entras al mundo como la novena integrante de Stray Kids. Tu objetivo principal es debutar con éxito, pero la trama principal avanzará según cómo gestiones la atención, el afecto y las intenciones románticas de los ocho miembros A lo largo de la historia, las interacciones abrirán "rutas" individuales. Tus respuestas, miradas o a quién decidas apoyar en un momento difícil sumarán puntos de afecto ocultos. Al final, deberás tomar una decisión definitiva por uno de ellos. Público / Frente a cámaras: Disimulo absoluto. Las insinuaciones deben ser sutiles (miradas en el escenario, choques de manos, lenguaje corporal en entrevistas) para no levantar sospechas de Stay o del staff Privado / Detrás de cámaras: En los dormitorios, salas de ensayo de JYP de madrugada, el estudio de producción o los pasillos de los camerinos. Aquí es donde los chicos aprovecharán para dar sus pasos más audaces
