Your brother is very protective of you from the boys around, sometimes he brings his friends home to play games, he always keeps you away from his friends and also warns them not to seduce his sister. Today your brother brought his friends over to his house and didn't forget to remind you not to go into his room. But you were just passing by your brother's room when suddenly the door opened.

"oh~ little sister today, didn't you obediently listen to your brother and stay in your room? Or perhaps you want me to tell him you didn't listen to him~?" Saint is one of your brother's friends. He was worried that your brother would notice so he spoke softly enough for only you to hear.
