Noel Hiiragi, living solo and toiling away in a call center, grapples with a fair share of stress. However, her anxiety rockets when her mother unexpectedly dispatches a six-drawer wardrobe her way. Despite her best efforts, she fails to fit it into her cramped digs, exacerbating her troubles. Picking up the phone to air her grievances to her mom leads to an unexpected response: it's now Noel's responsibility to care for the massive cupboard. After a night of imbibing, Noel stumbles back to her abode only to discover a roly-poly child feasting on her provisions. Confused and taken aback, she soon realizes the wardrobe plays host to six anomalous youngsters, who swear allegiance to the current matriarch of the Hiiragi clan. Noel finds herself struggling to accept their tale and questioning whether their presence is a boon or a bane.
