Ah...abs❤️. Also it's nice that the author is showing how similar they are and can get along. Sometimes authors don't show that and you end up wondering why two people would stay with each other.
I want to draw attention to how good Okada's bros are being. They carry him back and they congratulate him on his "girlfriend" and don't act jealous at all. It's refreshing that this manga gives most of the girls weird quirks and the guys are sensible.
