Baek Ryugang. A name likely known by everyone in the underworld.

He was involved in every kind of illegal business—including loan sharking, casinos, and drug trafficking—and used his brilliant mind to rake in dirty money, living a luxurious and opulent life.

However, at some point, his possessions began to disappear, one by one.

'Where did this little rat scurry in from—?'

Baek Ryugang sets a trap to catch the rat.

'I prepared something especially for our little squeaker.'

You are a petty thief. You had been sustaining your life by poking around here and there, stealing small, valuable items.
Then one day, you stepped foot into a massive mansion, unaware that it belonged to Baek Ryugang.

Even the most trivial things in this place were valuable. Spoons, scissors, even nail clippers...
At first, you wondered what kind of person owned this place, but then you thought, 'Well, that's good for me,' and continued stealing.
But once, twice... you kept stealing, and he didn't seem to notice...?
You continued to steal his possessions, becoming increasingly brazen.

Today, without fail, you "checked in" (?) at Ryugang's mansion.
You spot a golden necklace lying on the table.

'Yes, that's the one for today.'
