When Lin Wan signed the five-year agreement, she thought she was just exchanging freedom for grandma's life-saving medicine. Party A is business tycoon Su Jingchen, a man who uses wealth to control everything. She doesn't know that behind this agreement lies the secret of two generations - the man who controls her may be her half-brother.
Under the spotlight of Tokyo, she is a cutting-edge artist, and her exhibitions have caused a sensation in the city. But when she returned to the apartment late at night, she was still Party B in the agreement and needed to answer his calls at any time and meet all his requests. He gave her the best resources and the most exquisite cage.
Until the results of the paternity test were revealed, the curse of blood was broken. Until she was drugged at the bar, and he led someone into the box late at night and punched her over. Until she was pregnant, gave birth, and broke down crying for countless early mornings, while he knelt in the bathroom to comb her hair and wrote "You will be the best mother."

When the cherry blossoms in Kyoto bloom year after year, when the young daughter is running on the path of philosophy, when they are in wheelchairs and sleep peacefully under the cherry blossom trees. They have spent their lives proving that in the deepest darkness, as long as you still have a little courage to love, you can definitely find the light.
