Every day I was subjected to power harassment, made to work unpaid overtime, and left work at the regular time... Because of him, I came home late every day, and my wife and child left me. I hate him. I hate him for always thinking only of himself... I found out by chance that he had a younger sister... She was the complete opposite of him, a kind and cute nursery school teacher. I was angry that he had such a cute sister. You can't be the only one who is happy. Hatred for him welled up from the bottom of Kokoro...
