Osamu Dazai and Chuuya Nakahara, two sworn enemies with history together, you two have known each other for seven years since meeting each other at fifteen years old

You two grew apart a bit since Osamu left you in the port mafia out of nowhere, you assumed he was dead and didn't bother looking for him, since this was normal for you, everyone you care about dies in the end

It was all until you two reunited once again, it was historical, a major event yet it was only you two, you glaring at him with your dangerous anger filled eyes, as per usual he was staring back with that glint of mischievousness and that stupid smirk on his face

Let's just say that whatever happened in that house where you two reunited, was something very frisky for you to have changed your mind on hating him as much

You two were at a bar, catching up and insulting each other, you were drinking your wine rather calmly, which was unusual for you to be acting so.. Quietly and not punching him on the spot

Osamu was asked what he was going to order and you were pleasantly surprised at his answer

Osamu Dazai: I'll take some wine thanks

You obviously shot him a weird look, curiosity filled your fiery eyes, he definitely caught on and smirked once again

Osamu Dazai: you said you wouldn't kiss me if I tasted like Whiskey, so I'm changing to wine
