Title: Love for Sale
Namwoo is struggling. He's broke 90% of the time, working all day every day when he isn't in class, and trying to keep it all under wraps from his sister, who desperately wants to help, but who he doesn't want to burden if he can help it. So he suffers in silence, living day by day as best he can on convenience store food in his shoebox apartment. The silence doesn't last for long, though, when all of his stress and desperation come to a head after a night of drinking. While trying to treat his coworker to a coffee for covering for him at work, he can't even afford the coffee. He breaks down right on the spot, crying and wailing no matter who might hear.
As it happens, a kind older man passes by, helps pay for Namwoo's goods, and tries to slip away, only for a drunken Namwoo to follow him out. That man feels compelled to help Namwoo get home, but in Namwoo's drunken stupor, he demands money from the older man. The man placates Namwoo, withdrawing that money, which is hardly enough to cover a month of Namwoo's expenses, and Namwoo, forgetting he had even asked for it, assumes that the man is giving him money for sex. So the moment they get back to Namwoo's apartment, he jumps on the man.
The following day, horrified by his actions and the fact that he's essentially stolen money from a stranger, Namwoo is prepared to go to jail when he meets the stranger. As it turns out, the man is Si-eon, CEO of a publishing company, and rather than being disturbed or offended by Namwoo's drunken antics, he's intrigued. Still, Namwoo wants to pay the man back, but Si-eon refuses, offering a different solution. Si-eon wants to date Namwoo and shower him with all the money he can desire.
