In v7 when Blake is getting all dolled up for the club date, doing the whole eyelashes thing, and Yang is just. Chilling. Checking out Blake. Not worrying about getting all pretty and stuff like Blake. No, all Yang does is get up to check her hair with a little hand motion while placing a hand on Blake's shoulder.

That little action - that "all I need to do is make sure my hair is on point" - is exactly the kind of One Thing guys do. Because I've pretty much been there when getting ready to go out for some event. Because guys don't worry about makeup; they wait for the girls to get ready. All they have to do is make sure the hair looks good and they're set.
