Even for Japan this is a little too "tehet, when he was a kid he said that he'd marry a grown man when he turned 20" stupid.... Like his hole family really thought "SURE!".
Just not for me doesn't even describe this stupidity, and it's not like we haven't seen this type of thing before. I think it's more that this author combined all of the dumbest, he's younger he's older tropes and made it worse/more annoying. Also that first (r@pe)se* scene is just retarted.
