I do want to understand why people have disliked the ending so much. I mean everyone was well aware of the possibility (and almost reality) of the series not ending in great terms.

Let's be serious: who hasn't ever been in denial or in denial about a potential relationship? It's totally understandable why Sheng Wang is rejecting his own feeling. Just try to put yourself in his place: you've never fallen in love with anyone and, now that the time has come, this someone has to be your best friend and even your """""""stepbrother"""""" (I hate people calling them brothers yuck)! Wouldn't you also be crazy? Try to see from the perspective of the character.

Furthermore, talking about capitalism reasons, you know pretty well that the team wants us to be as anxious and nervous as possible for another season. This the only way to stay with the hype up. We'll probably get another season. Taiwan does it a lot and, if they continue following the novel, the S2 will also be perfect. Please continue hyping the series to make it possible
