Pop song contest

on January 8th saturday, we did pop song contest. our class21 sing  a song named 'Heal The World'that Michael Jackson sang
We didn't get a prize. I was very sad Because our class practice a lot. But it was interesting! One of the team, one boy dressed like a girl and act like a girl. At the first I thought the student is a girl but my friend said"you know what that student is a boy"
I was very surprised. That boy's class got the first prize. The present for the winning team was 초코파이. Why no prize to our class?????????
