This is a fun read. A teenage grandson of a yakuza boss romanticizes the idea of an older brother and finds him in a local florist. A comedy of misunderstandings. I laughed out loud a few times!
This story is related to "Akunin O Nakaseru Houhou," which was the one where the money-hungry guy gets together with his fabulously wealthy friend, but he's kind of a dick? He's the older brother.
