Seraphina, a girl with a deep love for painting, had a happy childhood filled with stories and adventures shared with her best friend, Z. Before Z moved to another country, he promised her he would return, and she agreed to wait. Shortly after he left, her mother passed away, and Seraphina was sent to live with her aunt. Expecting kindness, Seraphina was shocked when her aunt treated her like a maid, forcing her to work hard and hand over all her earnings. Despite her harsh reality, Seraphina clung to her passion for painting. As a working student, Seraphina balanced her studies and multiple jobs, striving to earn enough money to support her aunt. As the years passed, Seraphina started to lose faith in Z's promise. 12 years after he left, she doubted he would ever come back. One day, her aunt faced a major crisis: a huge debt that needed immediate repayment. With no money to cover it, her aunt made a drastic decision to use Seraphina as payment for the debt.
