After getting married, Miyu moved into her husband's family home. As her husband grew increasingly busy, minor disagreements turned into constant arguments. Then, her husband announced a one-week business trip. Wanting to improve their relationship, Miyu brainstormed various ideas, but nothing seemed to work, leaving her distressed. When she confided in her father-in-law, instead of offering advice for marital harmony, he demanded she let him grope her breasts. Hesitant yet intrigued, Miyu began to listen to his words. Now, she faces a new challenge: how to mend their relationship—and what boundaries she's willing to cross.
