When she finds "someone lonely" at the club, she uses her body to heal them.

During her work at the club, she meets Kei, who reluctantly goes there with his friend. Even though he loves, watches over, and keeps an eye on his sister, Kei is very surprised to see that Mutsuki looks exactly like her.
