For me,this is my 2nd best version after Itazura Na Kiss by Yuki Furukawa and Miki Honoka,although i watched this version first when I was in second year high school,I came to rewatch this again but as we grew up,we may view some things differently,like for example Xiao Qin's character for me back then was a very cute and adorable girl but as time passes,i realized her negative sides,(her life only revolves around a guy and if something happened she cannot function properly already,her stupidity was not realistic,as the story itself isn't realistic,it's impossible that a genius like Zhi Shu will like a girl like her,she was a stalker but i think if it's on Zhi Shu's point of view since he also like her,(he's just using his brain first before his emotion) it's forgivable.
Nevertheless,it's a very interesting story between a guy with high IQ and a girl with high EQ.

Enjoyment - 10 (Because of their contrast character,it's really enjoyable to watch)
Soundtracks- 10
Story- 9.5
Rewatch Value - The story is really interesting so I've already watched all 3 versions from Korea,Japan and Taiwan but if you'll ask me which version has the most rewatch value,i'll go for Itazura Na Kiss(Kotoko and Naoki)
