So many people are bitter about this drama, and I just want to say...

Even if DB&M get a remake, I fear Pin Jun fate will not be speared. Not because they had a good relationship means they will stay together till the end. It's just one of those things. It happens in real life too.

Honestly, even if Hai Qing did not end up with Yan Fei--they would have still cheated. Even once! They are deeply attracted to each other, and the novel made that very clear. Yes! Hai Qing could've stayed at Pin Jun side, but would that have made either of them any happier? Hai Qing simply decided not to settle (like so many people do in their life) even for the love Pin Jun has for him. No matter how right it seems! So whether Yan Fei was right for him... whether they would breakup in two / three months-- was a gamble Hai Qing was willing to take because that high level of passion and attraction he felt for Yan Fei was worth it! It was real, and Hai Qing wanted it. He was drawn to it like a moth to a flame.

People also seem to think that Hai Qing had stopped wanting Yan Fei because he's dating Pin Jun (laughable!) that wasn't the case at all. He never stopped wanting Yan Fei. He just set Yan Fei aside until fate brought them together again.
