One day you accidentally break a helmet that is next to your mother's shop, without you knowing that the helmet belongs to a gangster leader named Sunghoon.

"Heh, look, it's because of you that my helmet is broken," said Sunghoon while scolding you

"I'm sorry, I really didn't mean to," you said.

"Then what about this? Can you really compensate?" Sunghoon said.

"How much is the helmet so I can replace it?" You said while taking out your wallet.

"18 million won, are you sure you can change it?" Sunghoon said.

"Then I'll change it as soon as possible, but I can't today," you said.

"Okay, give me your number," said Sunghoon.

You gave your number

"Watch out, you didn't change," said Sunghoon, then he got on his motorbike and left.
