You know when you read the reviews and really get curious if it is really that bad? Well, as I started with very low expectations, I was pleasantly surprised.

Yes, the quality of the drama is very low indeed. Even a school project wouldn't get away with some of the more obvious flaws. Of course, it is low budget, you can't expect stellar acting performance or elaborate sets. But a lot of the issues have more to do with sloppy filming/ production and complete disinterest in detail or set atmosphere than with lack of money.
Watch the red pillow for example, that moves in each scene, that should have been blatantly obvious to everyone. Sometimes cutting is at fault and actions, that should be in process (e.g. walking) start like someone said "Go". The Set appears as if some (female) crew member volunteered her apartment, and no one bothered to redecorate. Nothing against pink in the room of a guy who lives with his mother, but still, would the character as it is introduced really feel at home in that atmosphere? I would have imagined something much clearer in design, less frilly pink. And really, did no one speak English to translate what is written on the bedsheet? It says something like "Mrs. always right"! Could have been funny if it were a present of Ying Jiaming, but just like that? Naaahhh... There are more sloppy things like that throughout the drama (which does make it funny in a way).

The story is nothing special, but I've seen worse. Predictable and not original, but well, doesn't have to be. There are gaping plot holes as if things that were supposed to be in the drama were cut. I don't understand how the motivated Ying Jiaming from the first episodes transforms into that boring guy without any spirit later on. And why on earth would the heir of the company president end up in a coworker’s apartment if he is injured? A cheap hotel room would have made a more convincing set than that. Some of the dialogues are cringy indeed and I can't picture the characters as introduced saying something like that.

Still, all in all, it is a cute little drama that doesn't take much time to watch. I won't watch it again, but there are more dreadful ones out there.
