The episode opens with the discovery of a newborn baby possessing a rare seven-star sole pattern, marking him as the legitimate grandson of the influential Lowe family. A doctor confirms the baby's premature birth and weak immunity, advising the parents to improve the mother's well-being to enhance breastmilk quality and to avoid disturbing the baby’s sleep. Despite the mother's reassurance that the father sleeps alone and the child is not his, evidence of the distinctive sole pattern suggests the baby is indeed the man's son, heightening the tension around the baby's identity and future while leaving the parents confronting this unsettling truth.
