We're both college-age in grad school. On Monday- this fine ass girl walked past me in the library and I had to do a double take. She noticed the double take because she kind of half-turned around. She then walked by again 20 minutes later- might've even turned towards me, but I only noticed her after she was already 10ft past. Oh well.

I then choose a new study spot facing a big, clear glass wall on the same floor the next day. She walks past that and I look up, lock eye contact, and smile (I'm kind've caught off guard) she smiles and mouths "Hey" as she walks past and then disappears and I look back down to my work. Successful day.

Back in the library and I'm out in the open so I can see her again and make a move. She hasn't showed up yet and we're getting close to the end of the semester in a week or two. Because its a very tight-nit community of like 600 students in this grad-school. It wasn't hard to find her linkedin, and we have 4 mutual connections.

Would it be weird as shit if I just add her even though she hasn't told me her name and I just looked her up and found it. Or would it be ok because she seems to be interested, she knows I'm interested, and there's no other way to contact?
