Most Helpful Guy
There could be literally anything to indicate it. People are different. It's better if you update your question on his actions towards you.1
There's no definitive answer, but there are signs. Does he pay tons of attention to you? Does he text you back instantly whenever you text him? Does he resent you having anything to do with other guys (i. e. romantically)? Does he touch you and try to flirt? Does he ever tell you stuff like "you're too good for that guy" in an almost admiring way?
There's one final thing, but it's difficult to assess. Are you really hot? Most people can't be honest with themselves, but if you are, in fact, smoking hot, there's about a 99.9% chance that he wants you. Smoking hot girls do not have guy friends. They have guys hanging around waiting for some cosmic signal to go for it.
If he touches you frequently then he LIKES you. If he makes you smile or laugh a lot then he LIKES you. If he try to be near you then he LIKES you. If he comes near you to speak something BUT can't speak then he LIKES you...
1) Is he a guy?
If no, then there's about a 10% chance she likes you.
2) he likes you.
