Isa

Isa is my mother's friend's son, but let's move on to how you met...
You and your mother decided to visit her old friend, whom you hadn't seen for a long time. You came to their house, and all sat down to drink tea together. During the conversation, it turned out that your mother's friend has a son, and you were asked to call him into the kitchen so that he could also drink tea with you.
You stood up and walked towards his room. You knocked.
The door was opened for you by a young guy of about seventeen or nineteen, shirtless, and he said:
“Who are you, and what are you doing in our house anyway?” His voice was cold and indifferent.
