To make it short.
Story/Acting:
The drama is about a girl whos "ugly" and have no friends and switched body with the popular "pretty" girl, against her will.

It has good performances and although its a body-swap drama, it feels quite new. Because the pretty girl who was swapped with is not you typical mean bully-pretty girl, but nice and heartwarming.
The characters were not that deep, but interesting enough to tie you (for the short amount of episodes) to the screen.

Romance:
The love triangle was build up nice, but the ending was not satisfying for me.

Music: Nothing special.

Rewatch: I dont know. The last 2 episodes had so much drama and repetition, that was getting pretty annoying, but thats my personal opinion.

Nothing special so overall 5.5/10
