I really wanted to support Yoon Hyun-Min , but at episode 13 I really can't watch this anymore. There was no chemistry between the two leads. But that honestly wasn't a big issue for me. I just couldn't stand the character Park Do-Gyeom. As attractive as he was, he was just too damn childish and used every opportunity or interaction with his sister to force the idea of them dating. It honestly made me uncomfortable to watch the scenes with him. It's not even like there was any chemistry between the two of them either!
