Wow, am I giving a web-drama a rating higher than 8? Yes.
Don't expect this to blow your socks off, but I really did enjoy the storyline and the characters of this story. It's got a good balance of comedy (actual LOL moments), romance, and near-tearjerks (just the way I like it...not ripping out my heart but sad enough to feel something).
I was a really big fan of the character composition. Two main CPs: a more mature CP with deep love and loyalty for eachother, and a young CP with lots of funny and embarrassing moments. I'm a big fan of having those two CPs side-by-side (honestly, now that I'm thinking of it, it's really big brain bc dramas usually end up using a stoopid second CP to keep the mood up that everyone gets annoyed about. But with the age gap, it's all natural.)
Zhao DongZe plays the two MLs pretty well...the characters are quite different from each other despite their similar passions in art. Also, I really have no complaints about the execution of the Lu Ming-YouYou-Ma ZiXuan love triangle (I'm not calling this a spoiler...you can tell from like ep 1); which is quite shocking because it really could've been half-as*ed.
There weren't a whole lot of cliches, which is surprising for a web drama (the only one I can think of is a scheming SFL trying to win the ML. I'm not counting the love triangles bc the execution wasn't cliche).

Overall, enjoyable watch! I binged, but I can imagine pacing...I think a lot of the episode endings were minor cliffhangers so should be enough to keep you interested. Lots of things going on: kid getting into college for art, dealing with a new *situation*, and having a youthful romance; older guy battling sabbatoge at work and in his love life; all while they do this body switch thing (only a few times...not that much) trying to go unnoticed.
