The joke I was going for was that in marriage you inevitably will learn just to do stuff to placate your wife/partner. I know they're not married, but the meme is that they're dating and don't know it yet.
Also, no, this is not being a simp. A simp (Sucker Idolizing Mediocre Pussy) is trying so hard for but a crumb of that pussy that you spend exuberant amounts of money, time, and energy on a girl that couldn't care less, or that puts a lot on the line at the potential of getting a date, even to the cost of those around him and himself.
Simply having an unrequited crush or doing something that may seem "lowering" doesn't qualify here. All she did was tease him a bunch for them not referring to one another on a first-name basis. That was all the apology was.
He's not deifying her. It's just some banter between the two.
