This series is perfect in all ways. There are no flaws that I can point out. This is literally a work of art. The story is so mesmerizing and heavy. Even though the shooting only took place in one location and it only the characters talking, they did it so good. This is why you call a character driven story. The story of Wang and In was done so beautifully. Wang is a person that is doesn't have any ambitions and knows what he wants to do in life. But when he found the thing he wanted, he fights for it even it hurts him. It was beautiful seeing his growth. He looked like a cocky person that knows all but as you continue his story, he is actually a person that is lonely and yearning for love. In on the other hand, seems like a person who it intelligent, composed and rational but when hardship arrives he tend to run from it and avoid it. He is a coward and he stayed a coward till the end. It was nicely depicted that some people can't change no matter how much we try. In the end, In stayed in misery and choose to stay in misery. He never even said 'I love you' to wang. though his actions and gestures displayed it so obviously. It was sad to see this ending even thought it was highly predictable from the first episode. But I think it was a nice way to end thing. I am a person that doesn't like sad endings. I don't like reality to come with my fiction, but still I am alright that it ended this way. This series may not be for everyone, since it is a character driven story and only focuses on the characters. So some may not like, but if you're into things that are plot heavy and focus on the characters, with deep dialogs. You should definitely, no you MUST try this. The actors did such a splendid job. Pond is a terrific actor, when he cried, I cry, when he was happy I was happy. He displayed emotions of someone who is cocky but is lonely and yearning for love so well. As well as Nike. You may not notice it at the beginning but when it was an emotional scene, he did it so well. As well Mam, she made me annoyed of her and that was her character so she did a splendid job lol. The music also was spectacular. Like I said this series is a masterpiece so I am just repeating the words now lol. One of the best Bl, which I would say you can't even say it is a bl. More like a lgbt+ series. Beautiful, outstanding and a work of art.
