I should've listened when they said not to watch this drama. There goes 20 hours of my life. What kind of idiot thought it was a good idea to give all the character/romantic development to the strong, popular, happy second lead instead of the lonely, sad, and broken main lead. And lets not forget how he's shoved away by almost everyone in the series even until the final episode. FFS they only gave the poor guy 10 minutes of romance and it was the final 10 minutes of the show.
TLDR; Don't waste your time.
