A few years after my remarriage, I've felt uneasy ever since that unforgettable man I still call "father" came into our lives. Every time I see him fiercely opposing my mother, obsessed with his work, he dreams of living an independent and happy life with his beloved mother. Then, in late spring, nearing graduation, my father went on a business trip—seven days away. And in the past week, I decided to take a forbidden action: I wanted to build a close and inseparable relationship with my mother.
