If you're looking for a youth drama, this is it.
It's based on the late 90's to the early 00's and while I wasn't born yet through most of the years the drama displays (i'm a 2000's baby) I think it was pretty convincing.
Not to mention that the cinematography was beautiful, the characters are all well written. One moment you were mad at someone because they looked like the antagonist while one episode later you find yourself rooting for this person, because they deserve all the sucess.
And at the end you realize that timing is the real villain of the story.
Oh how I wish I could go back to my school days, I cried a lot while watching the taeyang squad together. Love their friendship, it's something I won't forget.
Thank you 2521, it was such a beautiful time. <3
