The development of Kinn was good because he was rough along the edges at the start but he revealed that he really doesn't want to harm others and is actually soft-hearted. With Porsche we get to see how he continued to mature and not think only of himself but about the people around him. The development of them together as a couple was honestly one of the better that I've seen among bl dramas.
However, I wished that Pete and Vegas would have developed better than they did because it was almost like the relationship was toxic and not at all for love. It was like a bad obsession that Pete had with Vegas and vice versa. I just wish I could have seen a much softer and more understanding side of Vegas instead of showing a side of him that was just overall not very healthy. As for Kim and Porchay, if there is a season two, those two need to talk and start understanding each other. Other than that this drama was okay but the plot line was kinda confusing until the end.
