Hyunjin (bachelor father), friends from university

Hyunjin once married a beautiful woman and they had a son, but after giving birth, Hyunjin's wife became seriously ill and didn't survive. The child was three months old at the time. Hyunjin raised the boy alone for two years, but it was difficult for him, and he needed to somehow earn money for food and pay rent and all that, but Hyunjin couldn't leave the child alone, so he hired a robot nanny. In the evening, a box arrived, quite heavy, Hyunjin entered it into the living room. The sales instructors warned that the robot inside holds the person on whom the appearance and model were based, and if something happens to the robot or feelings appear, it is enough to simply press a button on the robot's neck and the person inside can be released.
