(This review doesn't contain specific spoilers on this drama, rather from chinese dramas in general)

Two things to be aware before watching this:
1. This is mainly focused on high school, so don't expect a lot of romance or kissing scenes (China doesn't allow pre-college dating).
2. Time traveling and body exchange also aren't "allowed" so they always do it in a way so it didn't REALLY happened, sometimes being it a dream or s fiction.

If you're looking for a nice and cute high school drama, then I really recommend this. The acting is on point, the best one I've seen from any gender-bender drama. The ML acts like an actual shy girl, not just a "guy acting like a girl", and the FL is very charismatic as a boy - nothing is over the top. More importantly, they actually act like each other, it's very satisfying. Congrats to all the actors!
