Valid Love(2014)

Valid Love is a Korean drama that follows Jang Hee Tae, a fishery researcher whose seemingly ordinary marriage unravels when he discovers his wife is having an affair with a carpenter. Years earlier, Hee Tae met his wife, Kim Il Ri, when he taught biology at her high school—a relationship that has now settled into routine domesticity. The discovery of her infidelity ignites unexpected anger in him, yet he chooses to preserve his family rather than act on his rage. Valid Love explores the quiet devastation of betrayal and the difficult compromises people make to hold their lives together, examining what happens when passion gives way to resignation and love becomes something far more complicated.
