I loved the OTP right from the start! I think they portrayed the relationship from step siblings to lovers realistically and I did think they had chemistry! Thanks to a lot of skinship in the beginning ;) They started as very comfortable with each other and overprotective, but clueless of their feelings, to finally realizing they're not only siblings to each other. The show also has one of the best OTP kisses, in my honest opinion! Smoking hot. Story: The writer, imo, aimed to show all aspects of love: unrequited love, between family members and friends, best friends to lovers, in marriage, etc. - and was successful. Every character had its motivations and purpose in the show, as well as their own story, which is not always the case - gotta appreciate it. The second female lead was bitchy, but rationally, as in - I know what I want and I will get it, without some makjang, to borrow the word, plots, but frankly saying what she wanted to everyone. But... certain side stories I found uninteresting, especially in the first part of the show. The story is not packed with a lot of action - yet still manages to convey the confusion and the change the leads experience. The last part of the show was a total soap, which I think could have been avoided, but didn't stop me from enjoying the series! I hate such soapy elements, but was too invested in the OTP story to care, honestly, heh. Acting/Cast: I loved the main actress, but the male lead was just competent and failed in some "emotional" scenes. Others were fine, except for the second female lead's father who overacted. A very big surprise was the male lead's boss whom I hated in the beginning, probably because of his story, but whom I loved in the end. Music: Excellent! Love the songs and especially appreciated the lyrics in English, very appropriate and picked with the scene in mind! Rewatch value: Yes, in a year ;) With fastforwarding through the uninteresting bits with side characters.
