Am I overthinking?

So I've recently moved to University student housing and there is someone who has been ringing the doorbells of each flat constantly, long story short I thought that a guy in a flat above me called "Will" was doing it. Now I find Will attractive but I was quite pissed off at him as I thought he was the one ringing my doorbell. Towards the end of last month he added me on snap and he sent me a snap although, as I thought he was the one causing the disturbance, I left it on open. Over the days I realised it wasn't him and just as regret started to build up he snapped me again, randomly a few days ago. We've been snapping back and forth since and I now as much as I want to get to know him I'm confused as to why he just randomly snapped me again. Am I overthinking or could there be something there?
