Good: I thought it started out VERY good. I had some good laughs. The introduction of the first true meeting of the male and female leads was GOOD. It started to slow down midway through the 30 episodes, for me. I also thought the male lead bodyguard, assistant guy, was an excellent touch. I loved him. I liked the young guy that lived with the girls also. At least he had good insights was nice and did not give bad advice to the female lead. I also LOVED the closeness and intimacy of the male and female lead when she was helping him with his problem. That was when I saw the potential of then being in love and as a couple. I love the male lead, " maleness" and manliness by his pursuit of the female lead. I like a good , strong male lead. He is very handsome also.
Mediocre: The three female friends were fine in the beginning with their support of each other and giving advice. BUT as the episodes went on, they became too involved in the female lead love life. I thought they gave her some poor advice that made her become even more confused about her feelings for the male lead, which in turn caused a delay in them getting together. The brainy female friend definitely went WAY overboard with her spying on the female lead and the male lead private area. She would be charged with a crime in real life. I understand looking out for your innocent friend but sometimes those two other girls went overboard or gave bad advice.
Bad: The ENTIRE romance was ruined for me when the female lead still had a "crush" or love for her best guy friend (since childhood) all the way up until the 20 something episode. The story did not even have her showing or thinking romantic or liking" feelings" for the male lead until the 20 something episode of 30. That is too late. Also the constant "not sure of my feelings" and the male lead and female lead playing games of who will cave first in the last episode was BAD. They did not really " get together" or dated. I skipped over all the mom scenes. She gets worse mom of the year award.
