Takashi was sent back to his parents' house after making his wife angry over a trivial matter. The more I rushed to apologize, the angrier my wife became, and I couldn't resolve the situation alone.

Yuri, beautiful and gentle, healed my wounds; occasionally fighting with my spouse wasn’t so bad. As I was thinking this, Yuri arranged for a night.
