Bully-Golddigger became my stepdad

Lee Min-ju finished her studies abroad and flew home. She was the only child of Lee Woo-jin, who chaired Ijin Group, and the heir to the company. Choi Young-woong ran the chairman's office and was Lee Woo-jin's partner. He bought a Harry Winston necklace to give Min-ju when she arrived. The two of them had not been introduced when they argued over a parking space. There was a scuffle and the necklace was damaged in it. Choi Young-woong had known Min-ju at school, where she was quiet and near the top of the class, and he dealt with her on that basis. He was rough with her, and nobody had told him yet whose daughter she was.
