A hickey or something else?

When I hanged out with this guy I’m really into I saw something on his neck that looked exactly like this on the picture. I asked him and he said he fell and something hit him, but I didn’t believe it. He said “if I had a hickey would I really be hanging out with you today?” I just stayed quiet. It had small red dots so can someone tell me what it could be?
