I watched Theory of Love a while back, but never got the chance to review it.
This is yet another one of my rewatch shows for whenever I'm in just the right mood!
I think what I love most about this show is Third and the progression of following his feelings towards Kai.
The emotional portrayal is so beautifully done even when he attempts to move on, I connected with Third a LOT.

Kai definitely was a character that had some annoying parts, but for me it never really was about Kai, this entire show to me was about Third and his growth. This was his love story to himself.
One that everyone will write at some point in their lives.
Loved it!
