I did not get the ending I want but I'm happy with 'I won't live badly'.
The acting was great, considering it was a first project for most of the actors. I was drawn to this for Kim Woo Bin and Lee Jong Suk, but ended up with a few more favs, such as Lee Ji Hoon, Yi Kyung, Kwak Jung Wook and Daniel Choi.

It dragged on a bit in parts, but then, that is to be expected when it has to last 16 episodes.

Didn't think much of the OST, but it didn't get on my nerves.

If you don't mind high school dramas, give it a try.
Enjoyable and mildly tugs at your heart strings.
