Cool na Otonari ni Kasa ni Kashitara Itsunomanika Sewa wo Yakareru no You ni Natta Ohanashi

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 neighbour, 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.”

A relationship with a slightly sharp-tongued angel begins, starting with handing over an umbrella. From catching a cold and having someone take care of you, to making a meal for someone because they neglected their health, to joint work (cleaning rooms)…'
