[Kusayarou] Miboujin to Joukyuu Kokumin [xinsu]

A grieving widow receives a funeral visit from the servant of the wealthy elite whose family ruined her life—an 'apology' invitation that turns out to be a trap sealed with drugged tea. Mocked as a smug commoner who dared defy her betters, she's broken from proud mourner into a drooling, heart-eyed devotee who ditches her own waiting daughter to rush back to her new master's side. But her total surrender only sharpens his appetite, and the closing pages make it clear her school-age daughter is the next name on his list.
