This is not the worst thing I have ever seen from beginning to end, but it comes pretty close. If I look only at the main romance, then that's a decent 6/10 guilty pleasure with a minor twist, where the woman is the mysterious aloof one, not the other way around. The problem is that there is just too much padding. Later on there are episodes, where the main characters have less than 1 minute of screen time. Overall the part that I wanted to watch took up about 10% of the drama.
Even though the -extremely pretty- actors are okay in terms of acting skill, overall the characterization in the drama is just terribly bad. Most characters couldn't be any more 2 dimensional, I mean sure this is a fluff cdrama so I did not expect too much depth, however the writing is beyond terrible. Each storyline outside of the main romance and perhaps the hacker girl's stuff is dull, boring and uninspiring. The entire drama feels incredibly sloppy. It's like every second scene should have been reshot, but the director decided that it was "good enough" let's go home early today, which is a pretty big shame, considering that the production quality otherwise is quite good, they used high quality camera gear, hired a skilled cinematographer & the 2-3 original soundstracks were also up to standard.
There is also the issue of subtitles. The machine translated subs are enough to understand the story, but there are many fine nuances lost and there were times, when I couldn't make a sense of it.

I'm a bit baffled by some of the other reviews, perhaps ppl are just a bit too mesmerized by beauty? ^
If you are interested in watching a fluffy Chinese romcom look elsewhere. A Love So Beautiful, O2O, Put Your Head on My Shoulder are all infinitely better in almost every way.
