read commenters saying u need an open-mind or that "there aint angel or demons just humans" (well they used the word "bad-guys") and that's one way to look at this drama or life. but it would be untrue - yeah people will be people, and nobody is perfect - but being a self-centered d*ck that doesn't take other peoples feelings into consideration, is a bad-person! its that simple. so i kinda like the ending -
cause after everything that happened MAYBE at long last Hai Qing grew-up enough, to understand that he can't act the spoilt-brat for his whole life, he can't go around expecting others to take care of him and cater to his needs...
his deciding to leave and study in the US - going to his father. isn't only showing that he cares at long last for family - and the importance of that in his life. but that he needs to distance himself from the men that want to mother him - and the studying abroad bit, will also help him grow-up mentally -

if he stayed with Yan Fei, what would change? he would just substitute one babysitter for another cause Yan Fei would fit right into the role of caretaker / nanny / mother and Hai Qing will continue being the spoilt infantile baby. so the decision showed maturity on Hai Qing's part - and that is something to applaud.

Ping Jun doing the right thing was obvious - there was no way he or anyone could put up with the crap that was going on - no matter how much u love someone when u see that they keep going back to someone else that isn't u - u can't keep acting blind, deaf and dumb... and i'm glad that he did that for himself - just now hope his next partner will be worthier..

side note - read comments about Ping Jun being a better fit for Yan Fei (and if Yan Fei was a better person, i would be all for that. but he isn't - so NOPE) but everyone seems to forget how Yan Fei couldn't keep his eyes off Ping Jun at the photo-shoot or even before, when Pinky introduced her brother to her boss the first time. his wanting to tag alone to Pinky's birthday party was why? cause he sensed Hai Qing was gonna be there? plzz it was cause Ping Jun was, and he couldn't get him to come to the barbeque after the shoot. but whatever... this was a good ending for all involved if Hai Qing and Yan Fei ended up together, then i would be pissed and call this B.S. this was good.
