First part of the manga: The ml have a co-worker who's his friend too AND who's pretty weird as fuck (really), who seems interest in her wife (she hates him) especially after HE kissed her even knowing she was married and all and in + behind the back of the husband who was in the kitchen.
Second part: During the husband's business trip, he's gonna cheat on her wife with his co-worker/friend, they'll do it TWO TIMES and then once he come back, he'll tell all that stuff to his wife and tells her that he regret it so much and shouldn't have never done that even if he was drunk.
Finale part: After learning that, she goes looking for the co-worker then beat the shit out of him in the street and come back home to slap her husband about what he did (don't know if she forgave him for what he did, that was in japanese) then they stay together and continu they sex activities etc.
