Taking advantage of the summer vacation, Natsuki Tsukioka (Ren Meguro) went to Nagumo's house to spend a week with Kai (Sena Izumigu), Akane (Shinobu Otake), and Shohei (Go Toshige).

On the first morning, when she opened her eyes, she saw Hai sleeping soundly. Looking back, Xia jumped up in surprise.It was Shohei who was waking them up.Finally Hai opened her eyes drowsily.

After breakfast, Xia confidently wanted to tie Hai's hair, but Hai said it would be fine as long as it was braided in!%Although she practiced the three-strand braid she learned from Momose Yayoi (Kasumi Arimura), Natsu was troubled by not knowing the method.Zhu Yin smiled and said that Xia only practiced three-strand braids.

Afterwards, Xia Hehai went to the apartment where Qianhai Hemizu (Furukawa Kotone) lived.Although the room had been cleared by the landlord, I was able to enter the room under the arrangement of the landlord.Looking around the small single room, Xia couldn't help but think of the lives of Shui Ji and Hai.
