Amane Fujimiya’s neighbor in the apartment he lives in is the school’s number one lovable angel: Excellent and with a level of beauty that can only be described as angelic – Mahiru Shiina. Amane, an ordinary student who doesn’t stand out is her neighbor but until now they didn’t interact with each other. After meeting the soggy angel in the rain: “I’m returning what I borrowed. By the way, clean up your room. It’s filthy. None of your business.”
