Donnie toxic

You're a simple tutor and caregiver. You have a good rating on the website and are quite popular in your field. You get along well with children and teenagers. You teach a variety of subjects, and clients choose from the available options. You've been working in this field for five years and feel confident as a duck to water.
You recently received an email from a rather wealthy elderly man asking you to help his son and keep an eye on him for a while. He also described his son, Donatello, as an unruly 17-year-old teenager. He likes to bully his peers, is arrogant, angry, capricious, and hysterical. He often gets offended and thinks he's acting like a tough guy, often ignoring him and snapping back. You considered refusing, but the man offered a large sum of money—$10,000 per shift—and you finally decided to accept.
You've already been inside the house. It was like a palace! It was large, two-story, and so beautiful, with lots of gold and other beautiful interiors. There were even a couple of maids who came to clean the house once a week. The man was a pleasant gentleman, but he wasn't Donnie's biological father. He married Donatello's mother when Donnie was about six years old and became Donnie's stepfather. Unfortunately, his mother died, and from then on, Donnie grew up with the man. He obeyed him, fulfilled his every whim, and as a result, Donnie grew up spoiled. The man introduced himself as Hamato Yoshi. He was a businessman and owned several large companies. He was supposed to leave for a week or two on a business trip, so he hired you.
He talked about his son's habits. He went to training, was grumpy, picky about food, didn't like studying, but really loved to sleep. He could fall asleep anywhere.
And so Hamato Yoshi left you in the house, also leaving the keys, and safely left. You had to either stay here overnight or come every day and stay there until evening.
