Imagine you need to pay the hospital fees for your poor, sick brother.
What better way to do it, than working the graveyard shift?
I mean, the pay is high, and working in a konbini is not that much of a hard work, innit?

That's probably what Uijun thought when he first applied for his part time job, except that...he didn't think about the fact that the store was situated in a sketchy, dangerous neighbourhood. 
And needless to say, the store customers are no better. And night after night, poor Uijun gets bullied, until one night, a knight in shining armour makes his grand entrance.
Bum Geonu may be a knight at a first glance, but he certainly is not once you get to know him better: he swears a lot, smokes like a chimney, always says whatever comes to his mind, and above all, he is a dangerous gangster. 
You might think those two have nothing in common, but believe me when I say, you'll be surprised.

This is the story of Uijun and Geonu, and how they became lovers.

PS: Yes, I am back.
Yes, I am here to stay.
Yes, I know perfectly well I disappeared for an eternity.
Don't throw stones at me.
