Li Zhou, who accidentally lost his memory and was bound to the healing card drawing system, woke up with a soft and adorable three-year-old daughter, Tangtang. He went from being an ignorant newbie to becoming an all-around nanny by relying on the system. While tenderly protecting his daughter, he gradually uncovered his mysterious life experience, past crises and the truth behind the system. Facing stalkers, hostile organizations and layers of conspiracies, Li Zhou, who is usually gentle and healing, hides a yandere-like paranoid possessiveness in his bones - whoever dares to hurt his precious daughter will transform into the most dangerous guardian and eliminate all threats with absolute strength. In the daily life of drawing cards to become stronger and healed and grown, Li Zhou and Tangtang redeemed each other, and ultimately protected the warmth and peace that belonged to father and daughter.
