Otonari no Tenshi-sama ni Itsu no Ma ni ka Dame Ningen ni Sareteita Ken

Mahiru is a beautiful girl whose classmates all call her an “angel.” Not only is she a star athlete with perfect grades—she’s also drop-dead gorgeous. Amane‚ an average guy and self-admitted slob‚ has never thought much of the divine beauty‚ despite attending the same school. Everything changes‚ however‚ when he happens to see Mahiru sitting alone in a park during a rainstorm. Thus begins the strange relationship between this incredibly unlikely pair!
