A one week romance with a guy you’ve never ever thought of before! Chanwoo’s friend, who had implied that Chanwoo was incapable of holding hands with a man, bets that he wouldn’t be able to date a man for a week. Angry at his provocation, Chanwoo accepts the bet in the spur of the moment. Chanwoo’s friend then points to Eunho and asks him to date him for a week. However, Chanwoo, who has a guilty conscience, decides to disclose the bet to Eunho. “I would like to be part of that bet too.” “W-what?” Should we… date for a week?
