Kita-kun ga Kawai sugite te ni Amaru node, 3-nin de Share suru Koto ni Shimashita.

Présentation

They can't let go, but they can't control him...! To keep the handsome, freeloader Kita-kun (26), Touko (31, female), Minami (29, female), and Nishino (24, male) team up and come up with the answer: living in a share house where they can share their boyfriend!! They can't hope for 100%, and they can't stand 0%, so for now, being 33% each is fine. That's what they promised (or so they thought), and now the three of them and Kita-kun's life together, full of desire, begins!! (Source: Futabasha, translated)
