The first time I watched this show, I thought Tae Kyung was too awkward and the show was okay. But it stuck with me enough that I added the theme song to my playlist on Spotify and I ended up coming back to watch the show a second time. This is one of my top two Korean BLs at the moment. It feels sufficiently well developed and tackles some tough topics - but not in a way that weighs you down. It's also longer than most KBLs I've seen and much better acted.

Spoilers below:
Tae Kyung in definitely still awkward, but I appreciate his sweetness and his caring for others. I love the way Shin Woo cares about him from the sidelines, and how their relationship develops from begrudging classmates to friends and eventually to romance. Shin Woo loves quietly but fiercely, which is lovely. Da On is a good guy, but he's a doormat, and he lets his fear rule him. It's nice to see him get character growth about this. Everyone really gets developed as characters except Namgoong, but I wouldn't change Namgoong for anything. He's awesome the way he is. He's there to fill a certain role, and he does it with pizazz.
