Cheol-ho is a spinal cord injury patient who became paralyzed below the neck due to a sudden accident.His only guardian was his father, Seong-gyu, until he died in cancer. Seong-gyu, a wealthy man, foresaw that leaving his son with a large inheritance and no family would make him vulnerable to exploitation by unscrupulous individuals seeking money. To protect Cheol-ho, Seong-gyu legally acknowledged Ji-eun as his daughter after thirty years of estrangement. Upon gaining legal recognition as his daughter, Ji-eun discovers that she has also been appointed as Cheol-ho’s guardian. Even more shockingly, Ji-eun finds out that Seong-gyu has tricked her into a financial trap that requires her to keep Cheol-ho alive for over 10 years if she wants to be eligible for any inheritance. If Cheol-ho dies before 10 years passes, Ji-eun would not be able to inherit anything—this is what Seong-gyu’s will says. One day, the family is visited by Kang-hee, a massage therapist born with visual impairment.
