Just... ahhhhh Thinking about this drama makes me feel warm and happy! Kim Yo Han and Seo Yoo Yeon were amazing. I liked that the lenght of the episodes was not more than 25 minutes because it meant I could binge watch it easily and really invest in the characters! I do not know if I would rewatch it simply because I now know the ending. I always enjoy watching Korean high school dramas because it seems to be really different to the school system in my country. And of course the OST is the star (thank you Kim Jong Kook for this gem and SinBi for covering the song)!
