Most Jin Yong protagonists suffered difficulties with women. Let's have a quick recap:
Duan Yu - some random girl forced him to marry her, then turned out to be his half-sister; later, all the girls he liked turned out to be this way... or so he thought.
Xiao Feng - loved Ah Zhu, but loved by Ah Zi, whom he didn't like that way
Guo Jing - loved Huang Rong, but wanted by somebody else
Yang Guo - do I even need to say anything?
Zhang Wuji - I don't think I need to say anything
Linghu Chong - lost the girl he liked, got depressed
Shi Potian - got involved with a biatch early on via a mix up
Yuan Chengzhi - liked by a cross-dresser, as well as a childhood playmate
Wei Xiaobao - yada yada...
Chen Jialuo - OMG...
Di Yun - loved someone that was married to his enemy
Hu Fei - had quite a few admirers
...yada yada...

So, who is missing from this list?
Please find the missing person.
That person, who is a major protagonist, is the one that I believe that avoided the most problems with women, and his romance came out very smoothly.
