So I wanted to re read this manga. So the story is similar to an "omegaverse" where there are soulmates and such but it's NOT BL. So the MC is actually a girl who has the 'omega' characteristic and she transfered to the school where her soulmate goes to... Her soulmate is passing himself as similar to a 'Beta' character but his characteristic is a very dangerous 'Alpha'. The 'Omega' characteristic of the MC is often pitied as they devote themselves truly to their soulmates and the ML 'Alpha' characteristic is often related to murderers and serial killers. Their pairing is considered as tragic. I forgot the title and I wanted to re read that story hope you guys can help me.
Okay I found it! It's: 340 days. Synopsis: Lin is a Shut, destined to a life of undying love towards one person. Dosung is a Destroy, always on edge to hide the violent outbursts they’re known for. In this world, it’s not just the genetic, but also the psychological traits that distinguish them. Just as Lin is coldly rejected by Dosung, a string of horrific murders threatens their lives and the investigation creeps ever closer. Everyone has a secret in this society of differences, but can Lin turn Dosung around?
