I just finished watching this after binging on hours end with my friends and I've got no words to describe what I'm feeling right now. I had dropped it after watching 5 episodes in hope of starting it again after it airs, but didn't feel enough enthusiasm though something kept prodding me to watch it over and over and I'm damn glad I did.
I don't remember the last time something made me feel so fluffy and warm. From the start, I did not want to judge the acting as I wasn't close enough to figuring out the characterizations. Later I realised, F**k, they are perfect.
Woo TaeKyung is inherently silent, observant, straight-forward, honest and brave.
Noh ShinWoo is a fairyland dream every person would like to have, sweet, bad at expressing himself, a bit awkward and cute.
Shin DaWon was straight up annoying, suffocating and so fake that it hurt, his character development was drastic and beautiful.
NamGoong Shiwon is an angel with a beautiful smile and beautiful heart, quite a bit mysterious and lovable goofy.
Lee SooHee was toxic, quite stubborn and defiant, too possessive. But something I liked about her, even when she hated TaeKyung, it wasn't because she was homophobic, she was scared of being replaced by someone and that was it. Doesn't make me overlook her underhandedness and disturbing nature though.

The plot: Beautiful.
There was a lot of cringe in the beginning, but then it evened down and became so heartwarming that I nearly died of sweetness overdose. As a person who is not very fond of fluffy and sappy romance, I had no qualms watching and crying over this. Pretty and stunningly written. The actors played their part so well it looked like they were made for it. I could just feel the tangible love between TaeKyung and ShinWoo at the end and did not want them to leave from the screen, I wished i could keep watching them.

The love triangle: Most realistic and healthy one I've seen in a while. It made me angry, made me cringe, made me feel broken and sad and made me feel elated.

Noh ShinWoo: Hands down my favorite character, and nothing will change that. He's a perfectly constructed character, so well done that he might even feel like a summer dream. But that's what was needed to fill in between Shin DaOn's imperfections and TaeKyung's brutal honesty. He's someone I'll remember for long and long.

Special love to the teacher and Namgoong, they were both saviours, yet appeared human and had their own story and irreplaceable importance in the story, very unlike side charaters in many other bls.

I'm always going to remember the last episode, mainly TaeKyung and ShinWoo holding hands, looking at each other, kissing and just being in love with everyone, the people who matter to them being sweet and supportive.

It's a drama I'd want to watch again someday and smile till my face hurts from all that exertion with no regrets.
