I did not watch the Chinese series, so I will not (and obviously cannot) make any comparisons. I had no expectations on this drama, so I guess I just loved it as it is. Everything you needed in a high school romance drama was there: hanging out with buddies, falling in love, teenage crushes, good and bad teachers, school assignments, meeting (or not meeting) parents at home and extracurricular activities (sports, theater, singing).

The main leads were nice and cute, and so were the other 3 supporting leads. The male lead was kind of a shy, aloof and awkward guy who didn't know how to express himself and the female lead was cute girl who badly needed attention in a nice way. The friendship dynamics among the five of them was cute. I particularly liked the scene when they went out of town, and lied to their parents about staying overnight at each friend's house, and all sat down watching the evening scenery.

The acting was good. The female lead, Soo Ju Yeon, who is 27 years old, really did well acting as a high school girl. Kim Yo Han was also great, knowing that this was his first drama/film. In the last episode, where they showed behind-the-scenes, you can see how totally different Cha Heon's personality was compared to Yo Han in real life. Yo Han really looked like he enjoyed the dancing scene (at his best friend's wedding) so much, which was not the kind of thing you would expect from the quiet Dr. Cha Heon.

Anyway, I enjoyed this drama. Something nice and sweet, bringing back memories of your youthful days (as also mentioned in the last episode), Would I watch this drama again? Yes, definitely.
