<human>: Provide a brief overview of the text.

So this past weekend was our prom. Our school has taken in some foreign exchange students, so I asked this one to go with me. She is a girl in my grade from Mexico.

After we go with our group to eat and leave the main dance, we of course go to the afterparty. We both drink a little, but not enough to get drunk. She starting resting her head on me, saying she was tired and her head hurt so we sat down. After a while she started talking about personal stuff that she hadn't shared with anyone else. She gets upset so I hug her, and she sits on my lap.as I'm holding her, she whispers to me that she has feelings for me. Then she asks if I'm with her because I feel bad for her, or because I like her. I reply "both" (I'm a pretty smooth guy). So she says you know you have 4 months to ask me out, because I'm leaving in June. So I promised her I would do it soon.

So now we are at the problem: after school today I tried talking to her, only to find that she was upset. Apparently everyone saw that she was in my lap that night and spread rumors that we made out, had sex, etc. They also said that I was telling everyone that she was stoned and drunk. She was extremely upset by this and didn't seem to believe me when I said I didn't say that. What do I do? I know I like her, and want to get to know her more, but I need to fix this before I do that. What do I say?
