Most Helpful Guy
Go up to him, make eye contact, and say these words:
"I like you."
If you have an interest in someone, don't be afraid to let them know. Rejection is a scary thought, but what's worse is never knowing if it would have come to something special if you had just said something. Be honest with him, and more importantly, honest with yourself. This is your one and only life, if you think something will make you happy, persue it. Just prepare yourself for possible rejection. You might like him, and he might like you, too, but if he doesn't like you in that way you have to accept that. This is his one and only life, too.2
