In the early 19th century, a mysterious albino woman named Y/n (she looks 20 but is 40) hires a widow named Mrs. Dashwood as her companion due to memory lapses. At first, she offers care and assistance. Then, Y/n learns of the widow's tragedy from Sense and Sensibility and begins to save her family. A tender love blossoms between them. The closer they become, the less often Y/n forgets—love heals.
