@Mick96 Technically, yes. But Kafuka possesses every other member of said harem through organ donation, each time a person is possessed, they will look like her in the eyes of Nouzomu sensei and the other classmates. So in Nouzomu's eyes, his only love and wife is Kafuka, even if in reality, he's been marring and divorcing non-stop.
@Meichiri also one of them is the guy that was good at telling stories, which interestingly enough is also the Kafuka we see at the end of the manga in the Church
