Between Love and Revenge

Shirley was David's adopted daughter, and they had relied on each other for many years. Though they shared no blood relation, their bond surpassed that of a biological father and daughter. After David's death, Shirley, filled with hatred for the Shane family who abandoned her, became a tutor for them. She initially had the opportunity to seek revenge, but an unexpected revelation about her biological mother's enduring love for her led her to reconsider. Later, she discovered that she had stomach cancer. Being caught between love and resentment for her mother, she ultimately decided to sacrifice herself to save her mother's adopted daughter.
