When I first met the guy I’m dating he smiled and acknowledged my friend not me. Why would he seen shocked I remember?

It was three months ago at first he smiled at her and held the smile / eye contact and she smiled back and I looked at him and he just did a double take and then what was it. Our paths crossed weeks later on social media

I told him I remember when I first seen you, I remember saying to my friend he is good looking. and he looked shocked and uncomfortable like “oh shit” I mean I don’t care I’m not offended my friend is a lot more open and socialable than me so I’m not surprised
