Do you think this guy likes me?

[Tanmeran]

In the halls & in lunch this guy always stares at me. In the halls he glances and in lunch he looks at me and his friend also looks at me.
I admit, i have tiny crush on him but don't know how to approach him. i don't want to just say "hi" because that can be awkward. I also follow him & he follows me on twitter.
I'm an aquarius and he's a Capricorn.
We have never talked before .
What should i do ?

P.S. I'm a sophomore and he's a junior
So
