Quartet
Maki Maki, Sebuki Suzume, Beppu Tsukasa and Iemori Yutaka happen to meet and form a quartet. They even begin to live together in Karuizawa during the winter, but there is a big hidden secret.


A teenage boy suddenly shows up outside Nocturne and tells Suzume that her gravely ill father has little time remaining and wants to see her.
