10 titles in which a girl tries to catch her cheating bf/husband but it turns out to be a misunderstanding and she witnesses something wholesome


1. Business Proposal - SFL crashes her bf's mom and son's date while trying to catch him on cheating

I'm not sure if this counts so bonus: Nami Uraraka ni, Meoto Biyori

As Natsumi never try to catch Takamasa's cheating but she do secretly join a cruise trip with him on the boat and accidentally see him talk affectionately with a woman, but it turns out that woman is her husband's male friend dressed in woman's clothes.

Will think of another

2. Sword and Brocade - iirc

FL (Tan Song Yun)'s step-sister plan to ruin and take-over FL's upcoming marriage with ML as the second primary wife (the first is FL's dying step-sister-Ying Er-) but then ML and all people found that step-sister sleeping with a man.
