Three top wealthy heirs Zane Hale, Tate Bear and Xavier White had their assets frozen and were left stranded on the street to pass their family's survival assessment, until they were taken in by Mabel Sun, a night market boxed meal stall owner. The three hid their identities as top-tier experts, pretending to be poor and doing odd jobs during the day, while using their skills in finance, combat, hacking and medicine at night to help Mama Sun drive off bullies and outsmart forced demolition traps set by property developers. When the assessment ends and their identities are restored, the three team up to eliminate business rivals, give up the lavish life of the rich, and start a hilarious competition to win the exclusive right to support Mama Sun in her old age, putting on a warm, satisfying and absurdly entertaining comedy drama.
