Okay so picture Noya going up to Asahi like "I have a thing for bigger guys" and Asahi just tries to stuff himself while Noya's not around, but he always takes things overboard because he just wants Noya to be happy and he just really wants to put on weight fast because "Noya won't like me as much until I've put on some weight" Sorry just a quick headcanon rant!
ahh, this is great! asahi’s just trying so hard to please noya, and noya’s happy with him anyway but when he notices he’s just so happy?? he loves the fact that asahi is going to such lengths for him, so he’s always super attentive any time asahi overeats, rubbing his belly and planting quick kisses on his cheeks. and when asahi does start to put on weight, they’re both thrilled!
