INTPs with partners, how did/do you approach a potentially candidate?

I feel like a creep when I'm genuinely interested in someone, but I can flirt extremely easily when I'm not due to my choice of career.

Like, at work in the EDR, I see someone I'm interested in sitting alone but I'd feel like I would be invading their space by just sitting next to them. I'm usually in a corner somewhere waiting for my break to end.

Any advice is appreciated, and any stories are as well.
