At just twenty-nine, Eunseong is terminally ill. The hospital gives her six months to live. With her life set to end by fall, Eunseong chooses not to undergo chemotherapy. Instead, she begins to tie up the loose ends of her life— She quits her job, leaves home, and dyes her hair. Years under the strict control of her mother left her timid, joyless, and afraid. Now, in a moment of impulsive rebellion, she decides to do one more bold thing: Spend a night with a stranger. He’s the type who prefers fleeting connections without strings attached. Despite countless encounters, he’s never been in a real relationship. To him, physical intimacy is all that matters. And for Eunseong, he’s exactly what she needs right now. So she stays by his side for what remains of her final season. Because by the time fall comes— We’ll break up . I’ll die.
