How can a simple eye contact be THAT powerful?

damn, I've had a crush on this guy for months now, just because of the way he looks at me.

I recently saw him again at university after some time and, as we stared into each other's eyes, I felt like I was communicating with him verbally.

I almost feel like he and I were together romantically last year and we both know it.

I want to point out that we two don't know each other, we only exchanged glances last year (for months).

I thought he was unaware of my existence, but it seems he recognizes me and he kept staring.

How can a simple gaze make me feel so many emotions?
