The main story is more shounen ai, the extra makes it yaoi.
Summary: Akiha is possessed by a fox spirit and moves I with his relative’s family. One of the sons, Yukari, is beloved by animals, and that includes the fox spirit!? How will this story unfold?!
Spoiler alert: in the usual way! Although the fact that they’re related is off putting. Like they aren’t siblings and it’s never mentioned that their cousins, so I can only assume they’re distantly related. Maybe like 16th cousins twice removed or something haha
