I never enjoyed plain youth drama. I tried watching Youth Of May, Hometown Cha Cha and much more and they never really impressed me. I normally enjoy watching fantasy dramas mixed with romance but 2521 was extraordinary. Not even once was I thinking to drop it.

Gradually, every episode was like drugs. I was actually addicted haha. Every episode was really exciting and was really eager for their romance to start. Luckily, the directors and screenwriters planned the drama really while.

Music. The masterpiece of the whole drama. Maybe this is the only show that got me really into music especially "Your Existence." I was really disappointed at myself for getting "too" attached to the song because it just gives flashback of the dark times in 2521. But oh my gosh, the song was so good. Same with the others. They ARE masterpiece!

The ending was beautiful yet heartbreaking. I spoiled the ending myself actually. When I was in episode 16, I was telling myself "its okay, it might be a beautiful sad ending." I was correct, it was BEAUTIFUL. Other youth dramas was really dull because of their sad endings but 2521 changed me a lot.

I'll really recommend you to watch this drama if your into youth dramas because this is chef kiss!
