(TW??? Mentions blood?? I guess? Mhmm. This would make more sense aged up?)
Asahi never questioned Noya's outing nor when he came back late. Knowing him he'd lose track of time causing whatever kinda trouble he makes with Tanaka. He wasn't ever given a reason to not trust the other so he never bothered.
So, when he was up late working away in the small apartment he wasn't expecting for Noya to burst in all bloodied and bruised up. He looked exhausted but that didn't stop the guilty look he had.
(DONT MAKE HIM A KILLER, I SWEAR-)
