Search Results: short or long hair on guys

So I matched on tinder with a guy in my college course a few weeks ago. He's rather nerdy but he's atttactive so I'm sure he gets female attention. I'm cute too, but anyways, we matched before class started. We haven't spoken much on tinder, just that we shared the same class. He wasn't making a move, but kept me on tinder as a match. Over the weekend I cut my hair as short as my jawline, and dyed it jet black. It's like a short black bob with fringe bangs, but I style it with a big poof and kinda messy. It was a big change since I had lighter and longer hair. I look really awesome if I can say so. So we met for class today. Before class, for his tinder bio he had nothing, I checked I don't know why. Then, we had class, he saw me with my new hair, dressed really good... and right after class, I noticed he changed his tinder bio to "really edgy." Is this directed at me because he's trying to appeal to me? His photos are not edgy whatsoever and he is not someone I'd consider edgy at all. Im not sure if my style is considered "edgy" (I dress in all black with leather boots, and my new haircut is short and choppy and black, I wear winged liner and pretty heavy eye makeup normally). I don't know what's edgy. I just like black. Was his new bio aimed at me or am I taking it too much as a personal thing?
