This show is epic!
The story beautifully presented that gender does not matter, but it matters with whom you feel good and comfortable.
The main point is that we only live once and we should live the way we want and feel good. Nowhere in the series was there any hatred, shock, or comment about the attraction for the same gender.
The actors, scenes, camera, editing, script, play of light, and soundtrack were incredibly beautiful. I had chills several times.

Oh Jun Taek- Kim Ji Hyun was very sweet, kind, innocent, good, understanding, and intelligent.

Lim Ji Sub (Seo Jae Won) was very charismatic and handsome :D. Beautifully played by mimicry. His work with the camera was perfect. His character's story was one of those bitter and sad ones. And when a person looked at him, he wished him luck in any form. He looked so happy in front of other people and friends. But he carried the pain he experienced in childhood with difficulty and unevenness. He was looking for the meaning of life, joy, shelter, and a place where he would be able to feel himself.
