I think Hiroi realized that he doesn't want to share the two people he treasures. Though I think that Mine and Take will not be together unless Hiroi is in the mix because he's the glue that holds them together.
No they won't. The mangaka already explained that take loses interest in ppl that fall in love with him and take love mine because mine loves horoi and not him. Won't work without hiroi in the mix
Just fuck each other already! I want to see Shirotani melt into Kurose's caress.
