You are absolutely right. Their marriage will probably be a political one: to strengthen the ties of the Tokyo and Kyoto yakuza. Their definition of love and marriage is different to a katagi (person not involve in yakuza).
That's one reason why I think they will get married and "love" each other but not the typical marriage and love that normies know
I'm just going to remind everyone that this isn' t a Shoujo it's a Seinen. Yoshino is well aware of the fact that no matter how much they respect women, they are still trash, which is pretty realistic in a Yakuza Household. Also, did some of ya'll skip the extras of them as adults? Including the one where Yoshino wants Kirishima to give all his girlfriends chocolate on Valentine's Day lol. She literally gives no fucks in what he does, that's just their dynamic.
