How would you take this joke/dare if you were the victim?

A friend that you used to be very close with, but now drifting away and becoming merely friends, or even aquaintances. Both thinking that they secretly hate each other, then one day, after a while of not really talking nor hanging out as much. Was dared to go up to him and say that she loved him and was only hating him because she didn’t want to love him.

How would you feel after your friend told you that, and then after your reaction, was told that it was a dare and caught on video? Would you be mad? Hate them? Act as if it was really funny, and laugh, but think to yourself “that wasn’t funny one bit”?
