Kazuto failed to enter university and now does nothing. One day, he climbs up a mountain nearby to enjoy astronomy observation for a bit of relaxation and sees a meteor falls down. He goes to the site and finds three girls there. It seems they don't notice him and he eavesdrops that they are goddesses. They soon find him and get panicked because they'll be confined forever if someone else knows their identity. He decides to hide them at his house for a while, but an angel comes to his house and blames him for knowing their existence. He hears that there is an exception a goddess can tell her identity to her boyfriend and he tells the angel he loves each of them. However, the angel never trusts him and tells him to make baby as a proof. Like this, Kazuto starts living with them....
