Til death, or after.

Yandere!Dazai Osamu x Reader x MHA! Crossover

You were promised once,

To a man that seemed to have no lingering attachment towards the world and the entirety of itself, and you believed till the end that he held you in the same regard, too.

But who would've thought that before you closed your eyes for eternity-he had softly grasped your hand with a certain softness that seemed to have never existed beneath his bandages in the first place, just to place a kiss on your ring finger before declaring you his life?

For such an eccentric man, even marriage after death must be proceeded.

And now, his only desire for the world is to find one where you both would be in it. Forever interwined, even after death.
