McCree has a fetish of watching Hanzo eat
Hanzo use to not eat in front of anyone, taking food and going somewhere private like his room or the roof to avoid people.
McCree gets a fascination for it, Hanzo still possessing mannerism from his youth and the way he gets slightly flustered when McCree gets too close to watch him.
he esp likes it when Hanzo eats ramen and slurps the noodles up
