First choice was apparently Yan Kuan, who refused to shave off his hair and ended up playing QC's rejected modern fiancé... who funnily enough had pretty short cropped hair already, LOL. Second choice was Qiao Zheng Yu, but he didn't like the comedic aspect? YZ didn't think FSF would be good at playing the spoilt brat character, or something. He sure turned out okay. :P Though reportedly Yang Mi helped him a lot by pointing out what he was doing wrong.

It's from a photoshoot he did with FSF:


I'm so used to FSF with a bald pate that I'm still startled to see him with hair sometimes, LOL. And no, all of Mickey He's dramas have been YZ productions. YZ pretty much handed him his career; I think Mickey's debut drama was a YZ one.
