This drama is all about the love story of KMR and DKS. More of a romance drama. There's school bullying, high-school stuff, and others. I don't think I saw any more genre other than romance but this was a very interesting drama to watch. (It was in fact my first K-Drama I watched!)
The plot was unique, but it's more of a "friends to lovers" or "classmates to lovers" story... But the plot was kind of interesting.
The characters also had unique personalities. For example, KMR. She's one of the beautiful people in her batch but doesn't seek attention nor brag about anything.
The ending was as expected, KMR and DKS will fall in love and "live happily ever after". Since it is a love story, I kind of expected "Happily Ever After". And after all, it's a "friends to lovers".
The casts' acting was very good. They all played the characters greatly.
