23-year-old Anzu is a housewife in her first year of marriage. She lives an ordinary daily life with her husband, whom she's been with since college. She's become addicted to dating apps and has secretly had affairs with about five men so far. Her husband has no idea, and the 23-year-old man remains completely unsuspecting. His small penis and premature ejaculation leave her sexually unfulfilled, with her desires never fully satisfied. Despite murmuring "I'm sorry to my husband..." Anzu continues enjoying her extramarital affairs with a confident, carefree attitude.
