Facial Analysis: (Because I spent hundreds of hours doing Micro-expression training used by FBI interrogators, as a way to cure what I thought was social incompetence in me. Turns out I'm just ugly lol)
She doesn't like him or find him funny
As far as facial analysis. There's a micro-expression of sadness mixed with slight guilt, in her face, after he says "Our sense of humor is probably the biggest thing".
She doesn't think he's funny at all.
She doesn't genuinly laugh at any of his jokes.
When he starts to say "Wahah aahhh I haven't combed my hair in three years." She let's out a forced laugh by the time he's said "Waahh aahhh I" before he's gotten the joke out, as a virtue signal for the camera because she's focused on the camera.
In other instances when he's trying to make her laugh by saying "Eeah eehh I can't say biscuts." She's not focused on the camera, doesn't laugh and responds with an annoyed pissed off tone.
She only laughs at his jokes she's both looking at and focused on the camera. Female manipulation is that of a toddler. If something's not immediately in the field of view of a female they don't see it as existing.
She's doing this because she gets direct praise both online and offline all the time from people
When he says "When they find out she's my girlfriend, they go to the other end of the spectrum" there's a micro-expression of delight masked by a fake expression of sadness/empathy.
This is what she gets a kick out of: The ultimate virtue signal of dating this socially incompetent cripple.
She has virtue signalling routines she uses over and over
@2:50 Her, "We were at a restaurant like two weeks ago and Shane asked for the check". In this instance, both of their body language and facial expressions indicate that she has told this story MANY times. His is of forced half fake enjoyment with how many times he's heard the story. He doesn't really mind that it mocks him because he's use to it.
Her expression is that of forcing her entire persona to pretend like she's a perfect person seeing him as capable. Notice she pats him on the shoulder like a dog three times when she says "He's capable." She doesn't see him as capable at all, but she forces herself to pretend because she's getting so much out of it.
She has No Sexual Attraction to him
For the kiss, she has pursed lips, a clenched jaw, and kisses him on the side of the mouth. Her body language is tense and we see that expressed in all her muscles but especially her fingers tensed and pushed down on them. It's not a sexual romantic tension because in that case, her jaw wouldn't be clamped shut and she wouldn't be kissing him on the very side of his mouth.
