The Corn Villains on Karrot Market

Three-line summary

1. My wife, who suffers from a brain disease, runs a corn street stall.
2. I am rarely by her side because I am busy boiling corn to bring to her.
3. Every time I am not there, villains steal the corn.
   They pay for one bag but take 13 bags of corn.
   They buy corn and then ask for a refund, but they don't return the corn and only take the money back.
   Apparently, it is at the Oncheonjang pedestrian bridge in Busan.
   I wish shows like "Unanswered Questions" or "Curious Stories Y" would cover this...
