Got it, this Gotou woman is the type who likes to control things in order to suit her wants, putting herself above others to a point where it's harmful, caring more about herself more than anything. If she truuuly loves the MC, then she would have explained her agenda through proper conversation, not through these manipulative schemes that only arose due to other women showing interest in her boy-toy (or so she thinks). Either way, she went the wrong way about it, and it seems her meat will get burned from overcooking in the end. Good thing the MC has a good head above his shoulders... Unlike some people here, apparently, who only thinks with their lower head. Just getting laid doesn't lead to true happiness.
She reminds me a lot of the ex from "Ore no Himekutsu o Haite Kure".
