I started watching this and all I could think of was how did this get such high reviews?

The story of a "monster" immortal whatever being brought back to life by the FL's blood and then they become roommates. Since he had money that never made sense. In generally the seance ML and the FL's best friend we there only interesting characters. The FL lead was generally silly and annoying, with some redeeming moments. The ML was one of the worst actors I have ever seen. The stoic, unemotional ML is standard in Chinese dramas but he never managed to make you like him at all.

I admit by episode 10 I kind of lost interest and I was looking forward to this being over.

Also, the created a cliff hanger for a second season but then had different leads for season 2 so it was like 2 different people.
It's the worst clog hanger - after Princess Agents which didn't even get a season 2.
