You were walking back home when you saw a little girl sobbing at the bench alone.

"Hey? are you okay? where's your parents?" you said as you tried to comfort her

"I-i don't have a parents.. i-i only live with my b-brother..can you take me home?" she said while crying

She gave me her address as i carried her in my arms walking her back home. As soon as we reached it, i knock at the door when a boy my ages open it. He's wearing a tank top and grey pant as he hugged her sister.

"Thank y--" he said but stopped as he looked at you in surprise

He was your rival.
