Only God knows how this is 8.9 lol, I mean it's could have been 8.4ish ( without those last 3-4 episodes, especially the last one) but man oh man mdl strikes hyping an average show with no sense ending ( and lead up to it), The show turned from switch off your brain and watch and you will like it to, forget you have brain and keep believing it was really good to make up for all the loopholes, no sense things happening. I mean this should be at max around 8.1-8.2 lol. Yes it was entertaining (well atleast til 30ish episode) and I don't mind loop or average acting in some cases, but for complete 40 episodes it's just a show you won't regret watching nothing spectacular here with a typical no sense last cdrama episode.

Reasons why this is what it is :
1. Overcompensation by people as this started as underrated drama and people were surprised that it turned out to be good
2. No big traffic actor so no hate ratings
3. A feel good drama with no angst or scenario where main leads can fail or be wrong

No wonder it got average rating in china
