Eimi lives with her husband and her father-in-law. Although they have been married for 3 years, they still do not have children. Her husband uses cigarettes to relieve the pressure from his father and work, so every time he is stressed, he goes outside to smoke. Her father-in-law always wants to have a grandson, so every time her husband goes out to smoke, her father-in-law 'collaborates' with her to help her get pregnant.
