A few years after remarrying, I've felt cramped ever since that guy I still don't remember calling "Dad" showed up in our house. Every time I saw my stepfather pushing everything onto my mother and going crazy over work, I dreamed of becoming independent and living happily with my beloved mother. Then, at the end of spring, with graduation approaching, my father left for a business trip with only seven days left. And in the week that followed, I wanted to build a close and inseparable relationship with my mother, so I decided to take a forbidden action.
