This was a really nice drama. The main couple was very cute, and they had a lot of chemistry between them. Seeing them together put a smile on my lips. I loved them.
Overall, I found the story a bit slow at times, but I liked how the plot developed. It had no major conflicts beyond the romantic story and the personal growth of the protagonists, mainly the ML, who had to overcome some problems from the past.
The only thing I didn't like was that it seemed like she was always dodging his kisses, even though they had a long, solid relationship. That frustrated me a little. I don't know if this was because of the age rating of the series or because the actors are too young. Anyway, I think that "turning the lips away" so many times was unnecessary; showing the tender interaction between the two of them was enough.
I liked the other characters as well and I enjoyed learning about snooker in Asia.
