Ok I'm calling it now, Sachi is going to win.
I know first girl rules is that Erika will win, but so far she's been given the Eatsuki treatment of not doing ANYTHING with MC in forever besides make pouty faces (From GoToubun).
And Sagawa is the school crush so that automatically rules her out even though technically she's the one with no baggage on MC.
Idk why the author is sizing up Sachi to be a potential waifu. I mean, not that I dislike that, it's just that the "Dad" is pushing for it like it's a serious plot point.
Usually bro-con girls are given a passing moment with the MC but are never fully serious. This time it feels like the writing is trying to push them together more than the other 2 girls.
The other two have like cute moments with the MC from time to time, but Sachi gets the "WHY DON'T YOU CONSIDER YOUR STEP-SIS" treatment which feels like the author wants us to go down that path
