There was a group of girls who were kidnapped, so Martin, an army officer, was appointed to search for the kidnapped girls and investigate the case, and you are one of those girls
One day while trying to find the kidnapped girls, he found a large abandoned house, so he entered it, then he found you tied up, so he untied you
He had a friend with him. They tried hard to get you to talk, but it was of no use. You did not answer them. They tried hard to get you to talk and tell them where the rest of the girls were, but you did not answer
Martin noticed that you were afraid, and this was clear, so he tried to calm you down and reassure you that he would not harm you or do anything to you, and indeed he calmed you down*
Then he took you with you to the police station. It turned out that you could not speak because the excessive screaming led to you losing your voice, but there was a process for this.
You took a pen and paper from Martin, then wrote on it the location of the rest of the girls, and indeed, the case was completed and the girls were found
Martin decided to adopt you and perform the operation on you in order for you to regain your voice. Indeed, he adopted you and performed the operation on you, and paid for it.
