I loved this drama. The ML and FL did their job right. Surprised this is the ML's first adult role. Great job. I liked how they seemed very comfortable around each other as they realistically portrayed people who grew up together. The FL did it a little too convincingly sometimes with that and her tomboyishness. LOL, Plus she was very slow to realize her feelings for the ML, even with all the hints. Anyway, the slow realization of them falling in love, feeling each other out, and actually being in a relationship, I liked it. When they were in college was even better. It is GREAT that the director/writer realistically portrays the " liking/love" that college kids show. The hand-holding, hugging and even tastefully kissing/making out. Some of these dramas I've seen act like these college kids don't have these urges and don't even show entwined hands, hugs, or at least kisses on the cheeks. Rate 9/10.
Side Note: Please dress the FL in more adult clothing in college. I know she is supposed to be tomboyish but they could have put her in stylish nice pants and tops occasionally and not jumpsuits.
