i'm so pissed that I only just thought of this, and also that I haven't seen this done before, this is so stupid and cute and angsty and funny for Soukoku, picture this
Chuuya is spiraling going on a rant about how he isn't human, he starts saying how he doesn't have a heart or a soul
then Dazai suddenly stops him and gives him this confused and judgmental look and he says
"Chuuya of course you don't have a soul, you're a ginger"
this completely catches Chuuya of guard and he gets pissed of at Dazai, immediately telling him fuck off and throwing a punch, Dazai dodges and it turns into a playful fight between the two of them, Chuuya completely forgot what he was thinking of, what was worrying him, he's just living, enjoying this moment, that was Dazai's plan, he knew it would happen, because he knows Chuuya is human, he just needed someone to remind him when he forgot
i might write a fic for this, or maybe I'll draw it idk
