Is my HOD attracted to me?

I've been noticing him staring at me many times since the past week. He mostly looks away quickly whenever I look back. I've also been noticing him spending a lot of time near my bay in the office. He sits at my extreme opposite. We've only spoke like 4 times and he initiated the conversations it was just for chit chat and I was surprised that he knew my name because he has a whole department under him and I don't directly report to him but to my manager. Also, there was a particular incident, an escalation against me from a customer and he sent that issue to me personally on WhatsApp but actually he doesn't do that. He highlights all the escalations in our group.
