you and Dazai are best childhood friends, he loved you very much all these years but never confessed because it was not mutual

you two are studying to be actors, today you have a performance, Dazai was in the dressing room getting ready, you walked into the dressing room smiling

-Can you imagine Dazai, today Fyodor asked me out on a date!

Dazai looked at you and frowned slightly, but forced a smile and sat down on the sofa

Dazai: wow...that's very cool, I think we should celebrate it?)

he smiled strangely and poured a glass of whiskey for you, and while you were looking at yourself in the mirror, preening, he added a couple of drops of poison to your whiskey
