I like this one guy since i joined a training camp. We didnt talked to each other during that camp eventho he kept trying to talk to me. I was speechless when he talked to me. I saw how his pupil changed when we had eye contact. His pupil would grow larger. So since then i will avoid from looking at him.

After the camp, i found out that he already has a gf. I am disappointed, yes. But it always happen. When i like a guy, he must be a 'taken' guy. So i tried to avoid him as much as i can. I never look at him anymore. I will look at him secretly, especially when he stands before me. 

Today, orientation commitees (we both are part of this commitee) were practising the games that would be played during orientation. During a game, i fell bcs a guy kicked my legs by mistake. I laughed, stood up then went to my position. 

Later that evening, my friend said that my crush kept looking at me after i fell. He looked like he wanted to say something to me but he didnt bcs i didnt even spare a glance at him. He kept waiting for me to look at him but i didnt looked at him at all. My friend also said that he kept looking at me throughout the day. 

Why? Pls act like we dont know each other. Dont give me false hope. I dont want to be your friend. I like you. It hurts ㅠㅠㅠㅠㅠ

What should i do?
