This is cute and funny. The concept is really weird but I like it.

Nikaido is an introvert at school, no one can seem to get her name right. Interacting It makes her anxious but she doesn't mind at night she goes for walks and sits in her special spot to relax in the quiet and spend time watching dog videos. One night her popular classmate Kugo-kun appears. Though it isn't him! It is an alien in his body, who takes over when he is asleep. Despite being freaked out eventually she comes around and nicknames the alien Chiro-chan and they become friends. Things get crazy when Kugo-kun wakes up.
Mad right?
I like the unlikely 'friendship' and the complication caused by knowing there is an alien inside your classmate's body! One I'd like to continue to see where it goes.

Thank you to Netgalley and Kondasha for providing me with an eARC.
