Oh man I think Takuto LOOOVES pineapple pizza. Zenkichi would take anything with meat, basically whatever goes best with beer. Shuji would usually go for margherita I think, very classy. As for smoking... Takuto smokes VERY rarely, maybe once a month. He always has a pack on him tho just in case (he also probably has a vape lol since he's not the biggest fan of cig smell). Zenkichi used to smoke in his youth but dropped it once he became a father. He begun heavily smoking again after Aoi's death. He slowed down eventually, but still does it occasionally, maybe after a hard day of work. Shuji doesn't smoke often, but he smokes A LOT. Like if Takuto would do one cig per month, Shuji would do half a pack on one day once per month. Basically all of them are fucked, but Takuto is a little less fucked, but even then it's arguable since Zenkichi actually looks after himself, does exercise etc, unlike the other two doofuses
