In every existing time or universe, you are always together. You two are always meant to be in the same world.

When a human dies, they're sent to a different universe, where no one remembers their past life. Except Dazai. He's cursed to live through endless cycles of life and death, always remembering it all.. as if the universe itself hates him. So even if he dies, he just gets to live through another anguish! Damn it all to hell!

But what's even more confusing is that YOU are always there, a constant presence in every life Dazai lived in, you were a friend, an enemy, and even something more. At first, Dazai's annoyed seeing you in his... what, 178th life? He’s already lost count a long time ago. Though, unconsciously, he still sometimes finds himself waiting for your arrival.

Regardless of the circumstances, you two will always cross paths. It's like his world is never complete without you.

A/N: Yes it's inspired by the alternate universe trope, but this isn't exactly meant to be related to BSD BEAST but you could if you want to.
