Gao belongs to a band of anthropomorphic cockroach children living in the shadows behind a household refrigerator. His imposing size distinguishes him as the largest in the group, leading him to naturally assume a commanding, if overbearing, role among his peers. Together, they strive to forge peaceful connections with the humans sharing their home, though their overtures often clash with the household mother’s relentless crusade to eradicate their presence.

The cockroach children work in tandem, crafting inventive but haphazard plans to demonstrate their harmless nature—tidying cluttered countertops, repurposing discarded items, or leaving small tokens of goodwill. Their actions, earnest yet awkward, oscillate between inadvertently causing chaos and sparking fleeting moments of mutual curiosity, underscoring their struggle to reconcile their concealed lives with the human world they yearn to understand.
