He was (in it). and this was (BAD.)
Where to start:

The story I guess....bottom line and you don't find this out until later: FL is not very bright because she had a high fever when she was a child, so she forgets things, acts like a child and is easily manipulated. This explains a lot about why she is the way she is.
ML recognizes her as a girl he met as a child and never forgot. Why does he like her now? If you can explain this to me, I'd appreciate it.
Enter twin-in-coma-in- hospital-and-other- twin-has-to-act-like- her- to- save-a-contract plot device, and let the antics ensue.
Every single moment he is with her, he is manipulating her. Cuz he likes her, apparently.... Could he have done this entire thing differently and wooed her without manipulating every situation? Sure. But would the writers have been paid? No. This is supposed to be a comedy. Is it funny? Is it gross? I don't know. I mean, obviously it's gross. But there are funny elements to it. Harmless because she loves him? I dunno. He doesn't actually HARM her. Unless you think manipulation is inherently harmful. But that's more philosophy and I don't have time to ponder that.

Bottom line, If you leave your brain and sense of judgment at the door, if you're looking for a very fluffy romance that is somewhat amusing, and you're wondering if you can find another Luo Zheng drama that has twins in it, (or really anything with Luo Zheng) watch it.
