I Can't Stand It, Sister-in-Law

Yong-joon is all set to spend an uneventful summer vacation at his college friend Deok-hee’s place. So, he was not prepared for how hot Deok-hee’s mom, Mrs. Park, is. Blown away by her beauty, Yong-joon is increasingly drawn to her. He knows it’s wrong… but she is like a fine bottle of wine he wants to gulp down in a go. Fate works in Yong-joon’s favor when he finds himself escorting an injured Mrs. Park to the doctor’s office. Alone with Mrs. Park, the young, hot-blooded Yong-joon can no longer control himself and makes his move. But will Mrs. Park give in, or will he be rejected? (Source: Lezhin US)
