Seiji Yamada is a young Shonen manga artist who is a big fan of fellow artist Sono Hanasaki. When the two meet it turns out that Sono is a fan in turn, and it's a match made in heaven for the two young men...almost. Ueno is an innocent pet-sitter who is hired to take care of what turns out to be a young man on a leash. This encounter leads to a relationship much more serious than either of them had anticipated.
