Here is a heartwarming story.

Yes, this happened at an intersection in Busan last month.

A man waiting for the traffic light suddenly got out of his car, walked quickly to the vehicle in front of him, closed its open trunk, and returned to his own car as if nothing had happened.

The man was a 20-something office worker heading home from work in Busan.

He had been concerned about the open trunk of the car ahead throughout his drive, and when traffic stopped at the light, he ran over to prevent a potential accident by closing it himself.

A taxi driver in the car directly behind him at the time said, "He was like Superman," and posted the scene on social media, where the video went viral and garnered significant attention.

Netizens commented that his quick dash back to his car after closing the trunk reminded them of a "ding-dong ditch" prank, and even gave him the nickname "Trunk-running man."

They also shared warm messages of support, saying, "Such good deeds should be widely known" and "A small action prevented a big accident."
