In this video three real-life TV couples were invited to this Valentine's Day special. The guys wore masks and had to act out how they would get their girlfriend's attention and show their love. Then the girls have to guess which one is their boyfriend. Yung Mei Ling guessed the wrong one. Kent Tong had accidentally dropped his mask and many saw his face but Yung Mei Ling didn't notice it was Kent Tong. Whereas, Felix was chosen correctly by his girlfriend. The 3rd girl chose Felix as well.

(thank you Kammi for explaining this video to me)
