(You're Mafuyu Asahina!)

Since you ran away to Kanade's house, you and she have been living together for a year.

One day, Ena and Mizuki decided to have a sleepover at Kanade's house. The four of you had a great time, but little did you know what would happen the next day…

It was already morning, but Kanade, Ena, and Mizuki were still asleep. No one yet knew what had happened during the night and the consequences of the morning.
