I totally agree with you. I do believe that Guan Hong loves YLX but was afraid of the instability that his love offers. If I was Guan Hong I would choose Wu Long because even if WL was to die in the war (although we knew that was not the case) the Yang family would take of her and her brother. She will have family support; however, by choosing YLX if he was to die in the war, she would have no support. So it makes sense that GH chose WL in the end. That being said, I was rooting for GH and YLX the whole time because YLX is just too hot. YLX is the only reason that I continued to watch the series. The series is good; however, I normally don't watch long series because I lack the patience for it but YLX was such an eye candy that I have to continue watching the series. Normally I hate facial hair on a man, I love my man clean cut but I must say, that YLX is so fine with facial hair. I think Yuan Hong actually look better with a bit of facial hair to hide his baby face and make him more mature looking.
One thing I did not like about GH and WL relationship was how ambiguous GH display her feeling for WL. There was never any indication that GH even like WL and then Wham! she was in love with WL. I was scratching my head thinking when did their love even occurred or better yet, when did she start liking WL?
I do hope that Yuan Hong will do another series with similiar character like YLX albeit a good guy of course and he gets the girl in the end. I will definetly will watch his series. After watching the Yang series, I couldn't get enough of YLX and followed him to the new Legend of Condor Heroes. He is very handsome in the series but of course, since I'm an oldie, I still prefer Mui Kui Wai but Yuan Hong did a good job as the charismatic, charming, and scheming Yang Kang.
