I wasn't sure about the plot at the beginning, but i changed my mind after a while: with my surprise, I found it quite refreshing and interesting.
What really got me, is that there are some heartwarming scenes that really touched my heart, with deep meaning and wise life lessons.
I'm still amazed by the beautiful way they portrayed delicate topics in some scenes... Insecurity, discovering one true self, accepting it, fighting for your dream, facing obstacles, fear, courage...
Also, I was so excited about watching a drama that talked about homosexuality, which is still a topic rarely shown in Korea.

I think the caracters were very realistic, with complicated emotions and flaws, not perfect characters, but normal humans. The more episodes i watched, the more i grew fond of them. I really enjoyed the slow relationships formed between them.
Episode 5 was a little gem, just saying.

I think the directing was unique and beautiful, and the music was very pleasant and on point.

Almost every character grew and matured in different ways.
I loved the acting of the main ones.
Jung Il Woo: i already knew and appreciated him, and i think he showed great acting in this drama too. But i have to say, a character that i really loved was Kang Tae Wan, both for the personality and the actor, who did an amazing job.

Even though in my heart i was ready to ship the male lead with another character (you'll figure it out), i know it's still something portrayed quite recently in Korea, so i accepted it and understood that it was not meant to be.
The 2 protagonists clicked anyway and were really cute together (i actually quite liked her).
I was drawn to how their feelings for each other grew slowly, but inevitably (some scenes made my heart beat faster, thanks to the dialogues, the camera work and the choice of music, applause for that).

*LITTLE SPOILER*
Even though the main protagonist made a mistake by pretending to be gay (also, for too much time), i don't wholly condemn him for that: it showed clearly that it was because he wanted desperately to help his family, and later on he wanted to confess the truth, but couldn't because he wanted to help Ah Jin. It was a problem, but he didnt want to hurt anybody.
He was well aware of his wrong doings, and later on he started to hate himself because of them.
I think telling the truth knowing you will hurt those you care about, is one of the hardest things to do in life.
*END OF SPOILER*

In this drama the fact that the protagonist put himself in complicated situations, making the wrong decisions, just showed what a mess life is sometimes, and i liked that. The different developments were good to see.

Another thing i wanted to say is: the main lead defending gay rights at the beginning with emphasis was because of his gay brother, he spoke also having him in mind: he certainly loved him and cared for him, that's why he sounded so passionate at the beginning, at least i think this way.

Overall, it's a nice, well made, interesting drama.
