The acting was good. The main leads had decent chemistry and the story was funny and cute. Fairly predictable, but that doesn't really put me off. The OST was okay, I liked one song in particular. The second and third couples were good as well. The main couple, an actress and a doctor, it was all good minus one thing. The actress is supposed to be this cute and playful girl who is kind and sweet overall, but honestly, she could more likely be described as cunning and flirty as well as airheaded. While it didn't bother me in the long view, some times it was hard to believe a normal man who was smart and warmhearted wouldn't be frustrated that she's mature and kind one minute and childish and petty the next.
The second couple, the actress's manager and the doctor's best friend who is also a doctor. To me, this one was more annoying. They had okay chemistry but a lot of dramas have this habit of having the man chase after a woman that doesn't like him and go so far that he could be called a stalker, but we're supposed to cheer when she falls in love with him anyway? Don't they realize that most of the time, when a girl says no she actually means no? Stop writing the story with a girl who seems to really dislike the man but eventually falls in love with him even though he makes her so uncomfortable that she literally would rather move out of her apartment than live near him.
Third couple, this one was cute and had a reasonable amount of development considering how little screen time they had. They are the main doctor's little sister and the actress's friend who is a famous musician. I was happy to see them get together because I actually liked the musician and wanted him to be happy. Although, honestly in the first part of the show, the sister is the most annoying little brat I have ever seen. How she goes from childish, petty, scheming, and a screetching banshee of a crybaby to a cute and agreeable girl with a mature and caring attitude, I just can't figure out. To be honest, the only parts of the show I fast forwarded were the parts in the beginning when she talked or did her screetching cry. I wanted to smack her and tell her to shut up because she was hurting my ears. She overacted it to the point of being a nuisance.
The rewatch factor is pretty high if you like a simple story with a cute and happy ending. Just skip past the annoying sister until midway through the season and you'll be fine. Overall, a really enjoyable show with happy endings all around.
