This was rather sweet, with the innocence of youth but with a small element of “what happened”.
Lots of familiar plots and character-types we see in nearly every “young love” C-drama.
I would say it started off a bit stronger than it progressed. Kind of wished they had skipped a sub plot or two.
Good with short episodes, and even if I usually skipped intro and outro, the music was fitting.

This doesn’t really affect the rating, but it affected my viewing experience:
I watched this with subtitles on Youku, and some of the lines disappeared way too quick, and they often became very difficult to read on light background (white text no background/shading).
