Otonari no Tenshi-sama ni Itsunomanika Dame Ningen ni Sareteita Ken

Amane Fujimiya came down with a cold after giving his only umbrella to a girl he found sitting in the rain. He never expected the girl, Mahiru Shiina, to help him in return. Also known as the 'Angel' of his school and as his neighbor, Mahiru was determined to help him get better.

But when she saw the chaos that was Amane's apartment, the only thing she could find to say was "unsightly". However, she still set to work tidying up, cooking dinner and anything else she could to help him. From cleaning his apartment to cooking dinner, no aspect of the job was too small for the Angel, who was seemingly unstoppable in her care.
