Takatou Shinobu, brother lover. 25 years old. Living under the same roof are his older brother, Masaki, and his nephew, Kazuomi.

Kazuomi is a troublemaker who is suspicious of Shinobu's familial love for his father, and he always bullies Shinobu when Masaki isn't around. To top it off, he even does something like that…! Because they are "family," there are many feelings they cannot communicate.
