"I'll show you how scary men are"
The Yakuza brother's heat, kisses, caresses...
I know it's no good. Why can't I refuse even though I have it...?

Yukari Momose, a high school art teacher, says, ``History of not having a boyfriend = age.''
She is about to turn 30, and due to concerns from her parents, she attends a matchmaking party, but
She has a lively conversation with a man of the same generation. First, it was a crushing defeat.
Honestly, I'm not even positive about marriage yet...

Unfortunately, on my way home, I get tangled up with some thugs!
Yakuza dressed in black appear in the nick of time, and Yukari is saved by the young leader.
It was supposed to be the first time I met him, but I felt like I had met him somewhere before...?

The student I met again turned out to be the young head of a yakuza!?
After a doting proposal, they lived together under the same roof♪
