It's a piece of Japanese media.The girl who was least likely to win and shows her feelings the least is the one that usually wins. Yotsuba, despite getting the smallest amount of screentime, is shown to be the one who is the most supportive of Fuutaro. She wants to do anything and everything to make him happy. It's also clear that she's more than likely Rena.
Nino is going too hard, Miku is going too soft, and Itsuki is a snek who can't do anything.
Since Fuutaro isn't a hamburger, Yotsuba is the only one who can win.>>184493154
She is a snek in the grass tho.
