Four years ago, Emily's finance, who she grew up with, canceled their engagement. In an act of self-indulgence, she ordered a male prostitute. In the blink of one night, she ruined her reputation, her father jumped off a building, her family went bankrupt, and worst of it all—she got knocked up. Now, Emily went back to her home country with three children. By chance, she met the prostitute again, who was sitting in a luxury car. "Found yourself a sugar mommy?" She was raising three children all on her own while managing significant debts, whereas he, the prostitute who wouldn't wear a condom, was enjoying the good life? It was unfair! Emily decided to seek compensation from this unprofessional hooker! "For the next three months, you'll have to give me half of what you earn every day." He readily agreed. To make more profit, Emily helped him improve his physique and taught him how to seduce women. However, she discovered that whenever she was too harsh on him, her boss James, reputed to be devilish, would find fault with her. When did she offend her boss anyway? Wait, the boss looked a bit familiar?
