Okay so, you don’t want to be creepy or anything but look out for her body language, like little smiles your way, or if she adjusts her shirt or hair as soon as you walk in. Even if you don’t see any of that, there still is a huge chance that she likes you back. Like if you’re me, I stay absolutely silent, but I like to be around whoever I like. If you see these signs, that definitely means she likes you too. There are two ways to go about this.
1. Straight out, straight up. You find her and just straight up tell her that you like her! Easy as that. :)
2. Simple and subtle. You leave little notes or hints, like lots of compliments, or little notes. Also if you ask for a small favour (“can you hand me a pencil”) studies show that they seem to like that person more! :) good luck <3
