Episode 22 - S1.E22

After drinking with Moon Hyeon, completely inebriated Yoo Jin walks into his house drenched in rain. Then suddenly, he gets on his knees in front of his father, Director Yoo, and his mother Jin Soo-ja, and begs them to forgive him. When his mother asks him what he wants to be forgiven for, he replies that he cannot part with Moon Hee even if it breaks his mother's heart and even if she disowns him. Shocked and frightened, Jin Soo-ja asks Yoo Jin if Moon Hee is hiding something about her past to which Yoo Jin answers in the affirmative. After some thought, Jin Soo-ja asks her son if the owner of the barbequed rib restaurant was Moon Hee's old boyfriend and asks him about the extent of Moon Hee's relationship with him.
