Honestly my expectations were really low from this drama but it turned out to be a really good one.

Story: Story is simple, nothing new. The teams promote and solve the problems of their actors. First half of the drama revolves around the managers and the main leads, second half involves the past of ML and the all the problems thrown at him. Last two episodes are really beautiful with all the good people getting rewarded for their hardwork.

Acting:
LSK: Is really knows her character well, she performed all her scenes greatly. Her chemistry with the ML is fantastic.
KYD: Played his role amazingly. He knows how to act as a star and be an immature behind the set. His emotional scenes were great to watch, he can get all your attention towards him.
Others: I m not seperately mentioning all the actors as there are too many. Actors playing the manager roles were really great, they had a really good dynamics with their actors playing actors. Other than these there were the side stories of others, who have to act as rookie, spoiled, confused, joyfull etc, which they did amazingly.

Characters:
FL: She is an amazing character who is kind of "hate" the ML but also cares about him dearly. She is a very intelligent person who gets the job done and know how to do it efficiently. She also supports her boyfriend and is there for him whenever he needs her even before they get together. Her dynamics with other people is hilarious and touching.
ML: A top star who is kind of childish yet a loving and caring person. Is has always cared for the FL and did things for her even without her knowing. Is gets jealous easily, wants the FL attention and does funny stuffs. He becomes a good boyfriend and a good friend/coworker to the people her works with.
Lawyer guy: Thought is would be a strict and annoying guy but her is actually really funny and good. His back and forth with the ML is fun to watch. He also has a good chemistry with the reporter lady.
ML' manager(KYS):A really sweet guy who is loved by everyone, he is trusted by everyone and he is really smart too. He really cares for his people especially the ML.
Ho Young: Cute, sweet and hardworking, she doesn't give up easily, deeply care for her stars. Her and KYS have a good relationship.
Others from the agency and Han Dae Soo: These are all good people, they are no antagonists, they are supportive and funny.

Likes: Great chemistry, great friendships and good romances. The ML is surrounded by good people who deeply and actually cares about him. The side story of YuNa and Jae Hyun is fun to watch. Then we have an actress who is a huge fan of the ML and she is really a good person. There is no good guy turing bad scenario. Last two episodes that showed the three couples and the funny moments with them. Everybody gets what they deserves at the end.

Dislike: They spent too much time on the story of someone wanting to destroy the ML, it could have been solved really quick but they kind of stretched it. Also they threw one after another bad guys towards the ML after the second half. Could have done better with the main couple after they got together. The mother returns and the dead friend story was also took way too much time.

Overall: It is a good light hearted romcom, which not just focuses on the romance and the main leads but to other characters and their story too. It has many funny, romantic, emotional moments. Acting and characters dynamics is great too.
