You ever watched The Accidental Couple? Hwang Jeong-Min and Kim Ah-Joong. I really loved it when it was aired even though most bloggers seems to give this drama a pass. The first few episodes was rather angsty (can fast forward here) but the show really gets going after the wedding. It's one of the rare few kdramas which gets better and better with each episode, with believable character growth and endearing characters who grows on you. I'll recommend it as a romcom.
