Description
Golden boy Seiichi has never failed in anything before -- until now, at least. After experiencing failure for the first time at this age, he might not be able to recover. That's when Ryuji makes a suggestion to Risa: "I'll get you pregnant in place of my brother."
《Story》

Risa has been friends with her neighbors, the Takeuchi brothers, for a long time.
Naturally, they were both into her.
Eventually, Risa married Seiichi, the older one of the two brothers.
The younger brother, Ryuji, acted like he was happy for his brother, but a massive inferiority complex was simmering inside him.
One day, Ryuji hears from Risa that, due to Seiichi being infertile, they are unable to have children.
Until then, Seiichi, the golden child, had never experienced any setbacks in life.
If his first taste of failure came at this age, there's a chance he'd never be able to recover from it.
Then, Ryuji makes a suggestion to Risa.
"I'll get you pregnant in place of my brother."
《Characters》

Risa Takeuchi (VA: Hina Shinomiya)

She's a little awkward around men, and she's only familiar with vanilla sex.
She's worried about not being able to have children.

No matter what he does, he does it perfectly.
He's also a genuinely nice guy who's protective of his younger brother Ryuji without looking down on him.

His feelings toward her haven't changed even after she married his brother.
