Without knowing how it happened, Tae-o gets stuck having housemates and learns more bad news about Song-i when he goes home for dinner with his family...

Tae-o contemplates what he overheard and is convinced he knows what it means. To show her appreciation, Ga-rin throws a party, which Do-hyeon attends.
