Bakemono-tachi no Iru Tokoro

A student named Agatarihito has recently started having dreams about eerie monsters. Due to a certain incident, he was ordered to stay at home by his school. At that time, he meets a man who resembles the monster in his dream and suddenly confesses his love to him. Thinking he was a suspicious person, the police took him to the scene, but it turns out he was no ordinary man.. It's a BL with a bromance between a student and a non-human.
