Synopsis
One day, my dad suddenly tells me, 'I think you're going to need a mother, Keita.' My mom died when I was little. I was upset at first, but I eventually came to terms with it. But why bring it up now...? Anyway, my dad introduces four women to me and says, 'The one you get along with best will become your new mother. You'll live with them for a while and give them scores.' I don't need a mother anymore, so I plan to give them all low marks. And so, I start cohabiting with these four women...
