100 Days with Mr. Arrogant

After being dumped 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, causing a scratch on his Lexus. He demands $3000 from her immediately. She manages to escape, leaving her wallet behind. Hyung-Joon tracks her down, insisting she pay for the car damage. 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. Eventually, she discovers that the repair cost is only $10 and plots her revenge. However, Hyung-Joon unexpectedly appears at her home as her new tutor. He continues to exploit her, but soon Ha-Young finds herself falling deeply in love with him.
