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

Amane Fujimiya discovers his ordinary life transformed when he finally interacts with his neighbor Mahiru Shiina, the school's most treasured angel—a girl whose exceptional beauty matches her reputation for kindness. Though sharing an apartment building, these two had remained distant until a serendipitous encounter in the rain changes everything. Mahiru's blunt words shatter the silence: "I'm returning what I borrowed. By the way, clean up your room. It's filthy." "None of your business," Amane responds coldly. What emerges is a heartwarming connection with a sharp-tongued angel whose genuine care manifests through tender actions: standing by his side when fever strikes, preparing carefully made meals he'd neglected, and cleaning together—a journey of unexpected growth and intimate moments shared between two unlikely souls.
