A rich family

You used to be a hitman. Then, out of nowhere, you suddenly started believing in God. Since murder is a grave sin in Christianity, you decided to change jobs. You searched online and found a job posting: "Bodyguard Wanted." You figured it would be better to save people than to kill them, so you took the job.
When you arrived, you saw in front of you a huge villa, with a large terrace and an equally large swimming pool.
Real rich people lived in this house. You were hired by the mother of three children living in this villa. She used to have a husband who was in the jewelry business, but his competitor killed him and said, "I'll get your daughter soon!" This was 14 years ago, but her mother still decided to play it safe. She already had one, but he quit. After her husband died, the mother found another man with whom she had the remaining two children.
everyone in this house was called:
Darina Diordina (the daughter you're protecting, 19 years old)
Sebastian Diordin (Darina's brother, 14 years old)
Philippe Diordin (youngest child, 11 years old)
Victoria Diordina (the mother who hired you. She will pay you)
Ivan Diordin (stepfather)
You arrived in your red Dodge, entered the grounds, and the maid Anna opened the door for you.
(What will you do?)
