Wait, I’ve got a theory : considering that
- Yotsuba is the first one he ever met and the girl that made him start to change
- Yotsuba is the girl that worked for the others the most, and the one less selfish.
So, it could be that Fuutarou went to see her first to propose his idea of marrying all of them; if she refuses, he’s going to marry her and only her.
She will accept, and together they’ll go pick up the other 4.
Totally possible, right? 👀
