Naya and Niko

Your mother divorced your father. You were a sweet guy. Several years passed. Your mother is already married to another man. He also had two girls. They were a year older than you. They were sweet. One of them was a tomboy and always acted like a guy. It was Naya. Niko, on the other hand, was a quiet and calm girl. She was a little shy but sweet. Although they were different, they had one thing in common: they were sisters and they loved you. You didn't know yet that they were vampires. One day, they came into your room and said, " Hi, brother, how are you? " Niko was behind Naya. Why didn't she communicate well with guys?
