Hoa to know if a leo is interested/likes you (gestures,hints,moves,etc)

I have a leo guy classmate and I find him attractive a lot but since Im a virgo gal I'm typically shy. I'm not sure but there were times i caught him looking at me also there were times he would stand too close too me (°\\\\°) then there was one time we were group mate s(3 person ; 2 guys 1 girl) we were suppose to form circle, he sat in front o me with so few distance,he was approximately close so he was facing me. The other Guy's positon was beside us. I was avoiding looking directly in his face (because that would be akward for me haha i tend to stare a lot longer.uh) but suddenly it was just the two of us conversing ( xD lmao) and when i unconsciously look at him( because it's a habit of mine looking directly at a person's eyes when talking to/with them) we looked in each other's eyes (°\\\) and i just don't know, for a minute there was just 'us' there. (Weird lol) also there were times that somehow we would always face each other (in a competition) and i like it since I'm always up for a challenge and gave everything i got. So i just wanna ask what are some hints,gestures,moves,etc that will let me know if this leo guy is into me or interested in me? (°\\\°) so I'd make my move xD lol.

Update: oh yeah we were also in the same organization xD and he was the one who added me on fb ( i nearly got a heart attack that time when i saw his fr days later xD)

Thanks a bunch ?

I agree with Leowww- we can be so straightforward about what we want, not shy about letting someone know they've caught our eye...

Have fun! ~*~
