Once a talented and promising pianist, Moon Chunghyun comes to Kang Taehwa's lending business, Kiki Cash, to borrow a large sum, too large for an individual.

"So, how much do you need?"
"Five hundred million won."
"Coming in strong, huh?"

Frustrated by Chunghyun's downfall, Taehwa is unable to keep a distance and clutches onto once-buried first love.
"You knew, didn't you? You knew I'd lose it over you again. You knew I'd chase you like some damn dog. Knowing this, why'd you come to me? Why?"
"For me... it was the best choice I had."
A twisted, yet romantic story, with support from the lovable employees of Kiki Cash.

"Anyway, Daepyung, ain't you curious why the boss’s been so irritable today?"
"Well, I don’t think there’s really a need to know why."
"I think… he’s got love problems."
"Huh? Love…?"
"Shhh, yer too loud."
"Oh, I’m sorry… But is the boss seeing someone?"
"Nah, I ain't sayin' he's actually datin' yet, but it's more like he’s baitin' the hook."
"Baiting…?"
"Yeap. Baitin'. But it looks like it ain't workin' out as planned. That's why things got all messed up. Understandable, though. Boss don't look it, but he's an MSG, you know?"
"Uh, you mean… NGSB, No Girlfriend Since Birth?"
"MSG, MSB. They sound similar anyways. Just let it slide, will ya."
"They’re totally different."
"Does that matter right now, Daepyung?"
