Really liked this so much at first, but the more it went the more unrealistic and uneccessary so much of the drama seemed to be. Also, I'm confused about a few things. Why did Hajin go after Dokyung so hard in the beginning if he didn't even like him? He was technically dating Jaehyuk at the time, and he denied it later in the story when Dokyung asked him if he was dating him, so that was weird too. Like the thought of being lovers was crazy, even though they were going out?? The way he pursued Dokyung made it seem like he really liked him. Also, they baby Hajin WAYYY too much. Like damn, I know he went through a lot of trauma but at some point he needs to grow up and take responsibility, also if he was in such a toxic relationship why didn't his parents step in? It seems like they didn't even know what was going on between Hajin and Jaehuyk, even though Taehyun was reporting everything back to the mother? Another question I have is does Hajin even know Taehyun is his uncle? That was never made clear I don't think. Also, when Taehyun and Dokyung went to meet Jeahyuk, how much Tae didn't intervene when he was getting the shit beat out of him? He has really good hearing so he obviously would have heard even if he was waiting a distance away.
I really did like it, but there were some things that were a bit confusing that really bothered me.
