Yuu moved from Tokyo to the countryside. However, due to an unfortunate accident, she lost her husband and is now considering remarriage a few years later. Upon learning this, her father-in-law was confused but recalled an old custom in the village: "A widow who marries into a single male household becomes a sex slave●." The father-in-law, who had previously suppressed his lewd thoughts, began to spiral out of control upon hearing about the remarriage. 'Sweet Yuu... I won't let anyone else have you...!!'
