Charming, pretty, and...a guy?! Yuu may have a bit of experience experimenting with crossdressing, but when a mix up leaves him wearing his sister's clothes one day, he finds himself catching eyes - and hearts too! Meanwhile, Kiriya is a shy boy who's only talked to Yuu in passing a few times; and certainly not while he was crossdressing! At first he even mistakes him for a girl...but maybe him being a boy is better after all? Plenty of hijinx lay ahead for our quirky lovers!
