"I'm so lonely, I've reached my limit..." Hikaru (31) trembled and burst into tears the moment we met at a Western-style house in Yokohama. The reason behind her pain was beyond imagination. Reflecting on her fourth year of marriage, the emptiness and loneliness she felt in daily life had left deep emotional scars. Desperate to fill the void in her heart, she turned to an affair. Yet, this romance ultimately became an unfulfilled longing. Even simple moments together—sharing meals, conversation—felt like pure happiness, but now those times are drawing to an end. What remains in her heart is a yearning for another life, and a desperate desire to cherish every moment with her lover, even as she fears the approaching end.
