I don't know where to start. The work they put into the characters to bring them to live was amazing! The storyline is well done, no filler episodes, no boring or unnecessary scenes - only enjoyable, adventurous and lovely scenes! I loved the way they handled the mental health topic which is why I loved Jaewon so much. The producers portrayed him so well! :) I also loved the love story between Jaewon and Jihyun. It wasn't rushed or too much, the perfect amount of emotional love, affection. I can recommend this drama to EVERYONE!! It was amazing!! ??
