My opinion, + mild spoilers

I can honestly say that this was the weirdest chemistry I've ever encountered in a BL. I know it's just acting, but onscreen, the 3 of them belonged together. The chemistry between just (any) 2 of them didn't really work. It was awkward. The 3 of them together, when they weren't competing, was amazing! I felt like I was watching friends who had grown up together and cared deeply for each other rather than people who had just met. There were jealous moments, but a lot of times when there should have been jealousy, it came across to me that they simply cared more about each other than they did themselves.

That being said, when Mix was feeling sorry for himself, I should have wanted to kick his butt. Somehow, instead, I just felt sympathy towards him. That says a lot about the acting in those scenes. As far as the rest of the acting, I think they would have done better with a better script. They were so limited, with everything literally being in-house, that it was a "make the most of it" script. To be honest, the best/most natural thing I saw in the entire drama was the initial kiss.

This is the first drama I've seen where, due to the chemistry of the characters, I was rooting for some type of poly relationship. After the first couple weeks of living together, they should have been looking for another place to live that didn't have a 2 person limitation. The happiness of the final scene and the possibilities ahead made the whole series worth watching. I assume there's not going to be a season 2, so in my head everything works out the way I wanted.
