Weathering With You by Makoto Shinkai

A runaway teen named Hodaka moves to Tokyo and, struggling to survive, meets Hina, a bright young woman who can miraculously stop the endless rain and bring out the sun; they start a small business offering sunshine for weddings and events, fall in love, and are soon forced to face the moral and supernatural consequences of Hina’s gift as her power takes a personal toll and the city sinks under relentless storms, leading Hodaka to make a desperate, sacrificial choice to save the girl he loves even if it means altering the fate of the city.
