This is a sweet and heartwarming story about young love. Watching the drama does require a large amount of suspension of belief because none of the characters look like athletes, particularly the so-called weightlifters. The swimmers also don't have the proper physique or form. (Why couldn't they have used a body double for the swimming scenes?) But the friends to lovers story is charming and well done, not least because Nam Joohyuk's acting is natural, relaxed, and believable. I could have done without the birth mother story line but luckily it didn't take up too much time.
