Three Mouthwatering Meals for Two

Dr. Cha Soo-Hyuk is a pediatric trauma surgeon who grew up in America after being adopted. Now he's back in Korea in search of his birth parents, but from the nosy strangers to the spicy food, he's having a really tough time! Then one day, he runs into Lee Yoo-Na, the owner of "Mouthwatering Meals" who has a fear of men. In an attempt to overcome her trauma, she cooks for him, and her food matches his tastes perfectly. Now, he only eats what she cooks for him, for all three meals of the day!
