For the cast, they've good chemistry even I watching their Behind-the-scenes. The ost so far they show us 3 songs but 2 has been released. It looks like gaeddong will end up with mahoon cause the story is about matchmaker live. But I'm scared that lee soo will become evil king if he didn't end up with his 1st love. Doojoon and that noble lady are one of my fav couple for this drama. You can see how they met and interaction so far so cute but it'll be more complex bcz of her father. And youngsoo is my favorite character in this drama, his reaction more like drama but at the same time it's looks like he has many secrets. So far I know thet he hiding some information from his friends, because he always saying kim soo name with lee soo(it's look like he already know from the start), he even know mahoon past, and he had more than 100 bottles of perfumes because his hobby is mix and match scene.
