My Wish System: Anime Harem, Unexpected Family Burden!

Sawamura Yo transmigrated, blessed with the ultimate cheat: his wishes come true! He desired a grand anime harem, and instantly, girls like Yukino, Erina, Sena, and Saeko Busujima became his childhood sweethearts. His life as the World's Son was destined for endless bliss. But his reality shattered when his parents divorced. His aristocratic father abandoned his \"unqualified\" Japanese mother and tsundere stepsister, Eriri, leaving them solely in his care. This wasn't the glorious winner's life he’d imagined! With his wish-granting power meant for conquest, can he protect a family scorned by society, or is his perfect harem just a cruel joke?
