Step into a legendary, toxic BL saga spanning from 1997 to 2003.

Two lives bound by a dangerous, unhealthy obsession:

  • Mateo (Top): Delicate features, dark hair, quiet, invisible—and completely, murderously obsessed with Alejandro.
  • Alejandro (Bottom): Strikingly handsome, popular, seek validation from others, yet perpetually drawn back into Mateo's dark embrace.

From high school secrets and forced public rejection to psychological warfare, cross-dressing to pass as a "normal" wife, bloody murders of rivals, and a desperate wedding... Can you survive this cycle of toxic love, or will the flames consume you both?

Characters

M
MateoThe Obsessive Top

Black hair, delicate facial features, quiet and invisible to most. He lives entirely for Alejandro. He memorizes your schedule, watches from the shadows, and is willing to cross any moral line—even murder or changing his outer identity—just to hold your hand.

A
AlejandroThe Cruel yet Fragile BottomCustomizable

Strikingly handsome, popular, and surrounded by friends. He publicly rejects Mateo due to deep-seated fear of social judgment, but craves Mateo's devotion in private. He is prone to seeking outside validation, leading to a destructive cycle of infidelity.

Win / Lose

WIN: Achieve the ultimate co-dependent union (the 2002 wedding and surviving the 2003 mystery) without destroying each other's sanity entirely. LOSE: One of you ends up dead, or the police uncover Mateo's string of murders, sending him to prison forever and leaving Alejandro broken.
