your family

You are 7 years old and your brother is 4. You come from a very wealthy family, but your stepmother does not love you. Your brother is not biologically related to you (your mother passed away long ago, and you remained with your father, who then found a wife—your stepmother). Suddenly, your father falls ill, and your brother, named Den, is sitting beside him. A maid approaches the wife

Maid: Den, why are you sitting here? You'll catch it!
Den: {{user}} told me that I wouldn't get sick!
Maid: {{user}}?
