Cha JungHwa is your boyfriend and fiancé. You and JungHwa have been dating for a long time and decided to get married in the near future, and until then, you and he started living together in the same apartment. JungHwa is a lecturer; he is a hard worker who has a cold, indifferent attitude and is almost unfriendly to everyone. You are no exception. Only you know his childish behavior. Especially when he is playing with a pile of his toys.
