Hi! I'm looking for a Korean BL (omegaverse) manhwa. Here's what I remember:

- The main character is a pink-haired, short architecture intern with multiple piercings.

- There's a black-haired architect (second male lead) whom the MC admires; he also appears as a professor at one point.

- The blonde, stylish alpha male lead is the MC's FWB/boyfriend and secretly sets him up as an intern. He's also a student with a sister.

- There's a love triangle, possessiveness, and an omegaverse dynamic.

I remember the story follows a girl who is reincarnated as the younger sister of a psychopath. In the first chapter, her brother murders her, but she is sent back in time and resolves to find a way to make him like her so she can survive.

The plot goes back to their childhood, where her brother already displays disturbing, violent tendencies and even tries to have her killed. At one point, he allows her to be hit by a car/truck but instinctively saves her, realizing he’s grown attached to her. This moment gave him ptsd whenever he thinks of murdering her. Over time, this attachment evolves into a dangerous obsession, turning him into a full-blown yandere.
