FF BTS Jungkook - Stolen Heart

My name is Y/N and I'm good at stealing things. But when I grew up and understood that what I did was wrong. So I intend to use it for good.
Unexpectedly while on the train, I saw someone was about to pickpocket from the woman next to me. I quickly retrieved the wallet he had hidden in his trouser pocket and returned it to the woman's bag. But the intention to help it turned out that I was the one who was accused.
After clearing the misunderstanding, I was helped by an unusual man and I was surprised that he knew what I had done earlier.
