Why did Sun say in "Idol Vortex Comes" that he never watched movies?

It was a game at that time, and then whoever lost, he had to call a friend of the opposite sex in his circle and let the other person say I love you ... Nana called Sun, and then Nana said, I hope Sun will say it. Who knows that eldest brother said that he had never seen a movie; Then I talked about Sister Xia Qing's film, and then Nana asked him to say three words. He said "I love her" and made Nana angry ... I think I should know that it is connected in the program, otherwise it is right to say that I like Sister Xia Qing. ...
