This lowly reader is fulfilled in wholesome parts, but the stupid sometimes outweighs the benefits. A running gag can make you gag so much that you want to throw up.
Uh...this sauna chapter made me remember Asu no Yoichi.
In that a deliquent guy that was part of a gag duo was slowly morphed from a normal guy into a chibi character and then into a girl that and even his street bro was surprised from the reveal, because of course he was originally a dude and the author simply decided that 3 regular guys in the cast was too much and genderbened the poor sap
as they were mostly joke characters their appearance wasn't regular and probably some late reasers don't even knew the origin of the new girl, the physique was literally changed for the sake of more harem
