Five years into marriage with her banker husband, Oobuchi Karina (33), works at an advertising agency. Before marriage, her husband was highly sexually proactive, always suggesting new ideas to deepen their intimacy. However, after marriage, he became fixated solely on having children quickly, and all the previous passion and excitement disappeared. She initially wanted to share more extraordinary moments and build a more thrilling relationship, but that desire was lost with marriage. Now, those days feel like nothing more than distant memories.
