The protagonist Tenko has her first boyfriend.
Her childhood friend, Ouma Sota, finds out and, in a fit of dark jealousy, rapes Tenko.

Naturally, rumors spread quickly, and Sota is teased by his friends.

"I knew it was only a matter of time, but isn't this the first time a girl has hated you?"

"And there's one more thing I don't want to believe..."

What action does Sota take after hearing his friend's comment?

Their relationship has progressed just a little since the previous work.

This time too, Sota loves Tenko too much.
