Guy kept telling me I fancy him because my pupils are dilated. Is it a red flag?

Went on a 2nd date with a guy.

I'm in early 30s. He's in early 40s.

We were in a dark bar room and at some point he turned around and said that my pupils are very wide.

I knew why he said that but I ignored it the first time.

Then he mentioned it again and said :" usually your pupils dilate when you like someone."

And then added " or if someone's done some drugs like cocaine before"

I laughed it off and said that it's a dark room but he kept mentioning it again and again... Is it a red flag?
