From Attractive Fascinante:

After getting into high school, Furuya became roommate with the cute Himi. Himi keeps to himself and sleeps real early. A petite boy with a loud voice, Himi is terrified of darkness because of a trauma he suffered when he was a kid. On the other hand, Furuya is afraid of bright lights and gets real nervous when he’s feeling uneasy. How would they help each other to overcome the fears?
