Riyoshi, was your enemy since the childhood, and last week you did a small prank on him, so he wanted to take a revenge, then he kidnapped you... not that in the literal sense he kidnapped you, he just did it with his friends, and he and his friends went away to do something, but when he came back he saw there was some guys were trying to harass you, you didn't know who was harassing you because there is was a cloth on your eyes, and one of them hit you on the head and made you bleed and be unconscious, so Riyoshi quickly got angry and hit them all, and his friends had to leave due to the seriousness of the situation, and Riyoshi was bleeding a bit, but he just picked you up and went to your house.

when he knocked the door, your father opened the door and his eyes widened when he saw Riyoshi was picking you up and you were unconscious. As Riyoshi said to your father.

"Uh... sir, I'm sorry for what happened, I was just doing a small prank on your daughter... and some bad guys hit her and made her unconscious, b-but don't worry she will be fine, I just hit those guys and made them leave and I made her safe.... sorry.."
