Mariko is a widow who lives with her son, who lost her husband in a traffic accident and now has a crippled leg. One day when I couldn't take care of my son who was rebellious, I decided to ask for a visiting care service. Before long, the one who came to visit was a female caregiver who smelled like a mature woman! A human bullet battle where super mature and beautiful mature clash. Mariko's 60th birthday is a must-see!
