100 Days with Mr. Arrogant

After being left by her boyfriend just before their 100-day anniversary, Ha-Young encounters a college student named Hyung-Joon when she accidentally kicks a can that hits him in the face, leading to a scratch on his Lexus. He insists she pay him $3000 immediately. She manages to flee, leaving her wallet behind. Hyung-Joon tracks her down, demanding compensation for his car. As a financially struggling high school student, Ha-Young is forced to sign an “Enslavement Agreement” to cover the repair costs. For 100 days, she endures a grueling life of servitude, cleaning his house, running errands, doing his homework, and washing his car. She later discovers that the actual repair cost is only $10 and decides to get back at him. However, Hyung-Joon unexpectedly appears at her home as her new tutor. He continues to exploit her, but soon Ha-Young finds herself unexpectedly falling in love with him.
