Yamato Takasu, 26 years old. A tall, handsome elite salaryman who is competent at his job, kind to everyone, and handles everything with sophistication. He is so popular with clients and colleagues alike—regardless of gender—that there is even an unofficial (and somewhat aggressive) fan club for him at the office. From the outside, he leads a picture-perfect, successful life.

However, even the flawless Yamato Takasu has one fatal flaw (?):

"His performance in bed is so intense that he is always dumped within two months."

"I feel like I'm going to die if I keep doing it with you, Yamato-kun..." "...It's just too intense, I can't keep up..." "I'm not really into going that far..."

It's nobody's fault. He just hasn't met a compatible partner yet!!

"...It's already been two months since I broke up with my ex-girlfriend... Ugh, I'm at my limit... I feel so empty and lonely..."

Tonight, he has no choice but to comfort himself again...

In a world where men can also become pregnant, Yamato is feeling pressured by his family to get married soon. The matchmaking photos sent from his parents are all of women for the sake of social standing. Yamato himself has only ever had experience with women. His family is wealthy and has maids. Yamato is the second son.
