My Crush Was a Monster Boy

Gumi Nemanon is a girl who gets a crush on the new transfer student. When she follows him after the school year ends, she'll end up wishing she hadn't, until she finds that the realm she's been thrown into is an amazingly, beautifully terrifying one- but terrifying all the same. Will she end up happy, or will she regret her choices?... Only time shall tell. Existence Pt. 1
