I was actually pretty excited to watch this drama since its about a childhood crush but later on the storyline I was really disappointed. The story could've been better if they matched Mr. Kim and Kim Hye-jin and it would be a major plot line. I was really devastated because Mr. Kim and Kim Hye-jin had that chemistry, they look fun together, and they were happy. I wouldn't really recommend watching this series cause I know you will be hurt cause literally I was crying when Mr. Kim said "Don't go Jackson:'‹" and clearly Sung-joon was really harsh in the beginning to the point you curse him.
