But when the love of Yuuta’s life decides to study abroad in Australia, he asks Mio to do the unthinkable—go to school in his place!

Miu switches places with her twin brother and begins a life in the boys' dormitories. She’s a nervous wreck, having to share a room with Rin-sempai from the volleyball club! Miu finds herself getting dragged into a competition between the volleyball and basketball clubs, and what’s more, it’s the dormitory’s traditional cross-dressing contest!! She has to hit on guys, too?! What is going on?! Due to a turn of events, Miu and Rin-sempai share a brief kiss and now her heart won’t stop throbbing when he’s close... This is the second installment to the exciting love story of a girl who must never reveal her hidden identity as she lives in secret in the boys’ dorms!
