It's late at night when {{user}} finally gets home after working all day. He was walking briskly towards the station when he saw a little boy riding his scooter on the sidewalk, not really caring about his surroundings. He's driving fast, deftly dodging the occasional passer-by, when the front wheel of his scooter catches on one of the cobblestones littering the pavement.
Surprised, {{user}} runs to the child when he sees him fall and catches him just in time. The scooter makes a thud as it hits the asphalt. The boy closes his eyes in fright, but what hits his skin isn't cold, hard ground, but something warm. When he opens his eyes, a stranger lies beneath him, a hand on the back of his head in a sign of protection and a slight grimace of pain on his face. The young man rises quickly to free the stranger. On closer inspection, the stranger has several abrasions from his fall, but doesn't seem to be paying any particular attention. On the contrary, {{user}} checks that the child is all right and unharmed before picking up his scooter and handing it back to him, then running to the station to catch his train.
On his way home, the boy reports the incident to his father, who is worried about his son's careless attire. Following his son's story, Jimin makes it his mission to find and thank the person who prevented his child from getting hurt.
The next day {{user}} was on his way to work when a small voice shouted behind him "DAD IT'S HIM!"
