As others have said, the subtitles are the absolute worst and are a real detriment to the series. Having watched a fair share of Thai series you can grasp where there are glaring problems with translation. Pronouns are a particular problem.

Aside from that, go in with no expectations and you will enjoy a mid level high school to college drama. It's both rushed and slow as molasses. I wish they would have spent more time on the college part and given more development with the characters at that age.
