Harrison Yu, 18, has lived his life largely out of the public eye. His dad, Harlem Yu, almost never talks about him to the media, while his mum, Annie Yi, would cover his face in photos with stickers whenever she posts them on social media. The former couple tied the knot in 2000 but divorced nine years later.

Then earlier this week, Harrison surprised everyone when he made an appearance as his mum’s dance coachin talent competition Cheng Feng Po Lang De Jie Jie.  It piqued the curiosity of netizens, who started digging for whatever information they could find on the teen.
