You stared, I melted

I was invited in a party last friday by a friend. I didn't expect that he was also invited and I did not thought he'd go. In the first place, I don't have the right to know. He isn't mine and I'm not his anyway. We're just in the same university, studying the same course and only classmates in one of our subjects. Yet I liked him. He's intelligent, charming, gentleman and funny. The problem is he doesn't know. And I don't even know if he likes me or anything. I don't know anything about him. So let's go back to the party I was saying. We played this game where we sat in circle and identify the "killer" just by looking at the eyes and body movements. He was right in front of me. In the first round, I immediately know he was staring at me and so I stared back. I suppressed a giggle and disguised it as a smile then I looked at the other players. My eyes should roam around the circle and I was back again to him. He stared again. Just like a little girl, I giggled then covered my face. I knew the alcohol was kicking in. Oh have I mentioned that in our class, I could see him from the side of my eyes and could see him looking my way. I just wasn't sure if who he was looking at really. Oh well. That night was also our first time talking at each other. 

I know that maybe this is just a misunderstanding of our eyes but I knew I melted. That I liked him that moment on. I just don't know what will become of this connection of ours and I know that it's bad to expect... I just want to let him know. I just don't know how to...
