I say turn yourself into a robot. Listen listen hear me out lol. Ignore ur emotions and ur feeling and turn off your insecurities. Walk up to them, say hi, introduce yourself and tell them you really like their work (or another compliment or ask what they're working on). Focus on asking a few questions. And just gage how receptive they are. If you stay in the present, it's easy to tell if someone likes you. Ask if you can sit with them during lunch, and share a few video editing ideas with them or cool videos on YouTube that were well edited. Or find out what they really like and discuss it with them. Add them on Instagram or snap.
After a few times of doing this, you put a pause on things, and wait and see if they reciprocate. Do they approach you, do they ask you to sit with them? This is important if you want something real and not something you have to force. It must be mutual.
What really helps me is I think what I wish someone would come up to me and say.
