RMAN-001 Stepmother Slave Namiko Ruri Saijo

Namiko became the wife of an ordinary office worker with two children. Her children continue to be very cold toward Namiko, who works hard at housework as her stepmother. One day, a new young tutor, Saiki, is dispatched from the eldest daughter Mari's Onedari. Namiko treats him with respect as her mother-in-law, but in reality, he is a nasty "trainer" who has driven many female guardians insane due to his repeated problematic behavior. I don't know anything about it...!
