First I want to say how amazing the cast of this show is. They all have great chemistry with each other and rlly bring their characters to life. Especially Lee Chae-min (Kang Ha) caught my attention from the very start and he truly gained a new fan of his person and acting with me. Did the series have major flaws? Yes. The storyline wasn't able to live up to its full potential, due to bad writing. The love triangle was very unnecessary, since it's unrealistic for a grieving brother to fall in love with the potential murder of ur brother.. just because the girl is pretty. Kang Has revenge should have gotten way more attention and detail. However apart from that each episode was very enjoyable to watch and it never bored me in any way. I hope they are able to do a season 2, where they stop focusing on the romance (or at least in a better way) and start the real journey of Kang Ha with the school.
