As for how Qingqiu Ah Li came to know Li Mufan, the Fourth Young Master of Demon City, it also has a 'blood and tears' story behind it.
Before the 'pure and noble' celebrity Bai Mo passed away, she indeed genuinely liked Li Mufan, Third Young Master Li. After all, he was handsome, and apart from being a bit of a flirt, everything else about him was good, so it was only natural for Bai Mo to fall for him.
However, what made people feel depressed was that Bai Mo's affection was unrequited. In plain terms, it was a 'one-sided crush', ah, ah, ah.
Li Xiaosan, aka Li Mufan, saw himself in a rather high light, and his 'requirements' for choosing a girlfriend were, naturally, even higher. Why would he easily fall for a woman? Most of the time, Li Xiaosan was just 'playing his role in social situations', and he had never really 'battled it out' seriously with anyone.
