Gakuen no Nemurihime to Soine Friend ni Natta Ken

Kanata Kurosaki is a high school student living a simple school life.

One rainy day, Kanata catches a cold and collapses on his way home from his part-time job.

“Are you alright?”

The person who saves him is Shion Yumekawa, a beautiful girl who is called the “Sleeping Princess” because she sleeps all the time at school.

“I’m so excited to have a friend to sleep with!”

“Since when did you and I become… friends?”

My relationship with her was only supposed to last for that one night.

“Will you be my sleeping friend?”

“What the hell is a sleeping friend?”

“Well, it’s a friend who sleeps with you.”

“…Sure?”

Since then, Kanata and Shion have been sleeping together regularly.

“Breakfast will be ready soon, so be patient.”

“Would you like to have a study session with me?”

“It’s like a date, just the two of us going out together…”

Huh? I thought you said our relationship was only about snuggling.

This is a romantic comedy about a lonely, gloomy protagonist who becomes involved in a lovey-dovey relationship with a silver-haired, respectful-tongued, caring, clumsy beautiful girl while sleeping together (without realizing it).
