Fuyumine didn't rush his bath, Kanako-senpai told him to go first last chapter especially for this reason.Why exactly did Fuyumine need to cut his time so short? Since he needed to walk longer, he got less time as it is. Surely the girls could have waited for him in the safety of the women's bath. Dude should have enjoyed the bath and sauna to the max. As it is, he's not even romantically interested in any of the girls, so he has no particular need to try to impress them or anything.
