Look, I love Feiyu and have waited for him to do a project like LAP, however, the plot of the ex-convict bad boy and the angelic good girl is one that Hollywood did many years ago and with much better results. It's a basic plot that needed something more explosive to keep it humming along.
Also and IMO, Jingyi was the wrong actress to pair with Feiyu because even when she's happy or playful, she always has a restrained manner about her as if her public image is more important to her than the character she's playing. Essentially, she acts the same in every drama of hers. How does she keep getting projects?

I see there's a lot of fangirling and comments like "oh my god, their chemistry" but honestly, only Feiyu brought the heat, Jingyi was all-around terrible as a romantic lead. The story is nothing special and the execution was even more lackluster. I hate when a series starts in the present and then takes almost 15 episodes to tell the back story through flashbacks. It's one of the laziest forms of storytelling because basically, the scriptwriter isn't confident that the story was good enough to build organically.
