i like to imagine that when Jotaro gains weight, he's nowhere near used to it. He gets around his house slow, he's almost always found practically waddling. he finds himself stuck in some odd, but compromising places (Kakyoin loves the sight of it), and he's always so tired and low energy. he groans when he sits or stands, sighs when he lays down. Jotaro likes to get an equally chubby Kakyoin on his lap to rub his upset belly when he's eaten food that just doesn't cooperate with him. Kakyoin knows the ropes better than he does.
requests inbox is still open if anyone wants to give me some ideas or headcanons!! i got an apple pen and a new ipad, it makes drawing more accessible and MUCH more satisfying (unlike my unfortunate finger drawing on phone set up)
