S5·E1 The Taste of Curry

Tucked away in a corner of Hongdae, Seoul, South Korea is the curry restaurant "Cat's Restaurant" run by Yu-Mi. She doesn't have very many customers, but Yu-Mi tries to stay the course. One day, Yu-Mi's restaurant is vandalized and she notices a guy standing behind her. Yu-Mi ends up knocking him out with her groceries. When he wakes up, the guy is unable to remember his own name. Until he regains his memory, the man helps out at Yu-Mi's restaurant.
