What does this mean?

I am 24 M, she is 21 F. We study at the same uni, she is 3 years younger than me. We both follow each other on social media, we like each others posts and stuff but we never talked at all.

We are on an event club at the uni, me and her and another girl friend of ours (I already slept with this third party before, but it’s not about her) had a meeting with some guys to do a collab for an event.

When we sit down, I sit in the middle, so both of the girls are by my side. But this girl immediately felt comfortable and she put her head on my shoulder while sitting too close to me, the other one kept a respectful distance and focused on the whole conversation.

During the whole meeting, her head was still on my shoulder and she touched my thigh from time to time and when she stops it’s like she is trying not to lose control or creep me out.

Whenever i start speaking she keeps her head on my shoulder turns her head to look at me directly and look up at me with dreamy eyes.

And when I talk to her directly, she looks at my eyes and looks at my lips, she also responds in a feminine tone.

When we stood up and prepared to leave she came too close to me and started rubbing her breasts on my arm, I tried to fall back but she still pushed and continue to rub them on me for a few seconds.

My confusion is that we never spoke before, this is the first time that we sit together and she does all this.

Also I don’t know if she does this with everybody or just with people she likes or see them as a masculine figure.

What do you guys think?
