The number of tropes in this drama is sky high, but luckily it's a relatively short drama so it's still palatable...
Yes, we got the some lead loses their memory (that's actually the setup of this whole drama so this isn't a spoiler)
and then we got some parents that don't want the leads to be together
and some jealous second leads / random girls
leads thinking the other lead is together with a second lead
etc
you know, we got ALL of these -sigh- (just missing the Korean drama kimchi slap and the water splash scenes lol

But I still gave it a >7 because Li GeYang is real cute and I'm glad that our second lead Cai Yasi (from The Love Equations) finally got rom com first lead and doesn't have to watch his best friend fall in love with someone else!!!
And the leads' interactions are pretty cute. When they aren't fighting.

I don't know. This is a good time filler and cure for the Cai Yasi second male lead syndrome. But other than that, there are much cuter / more original rom coms than this.
