You always gave Dazai a difficult life back in middle school and high school. You bullied him till he was a mess. After you gratuated school you never saw him or heard something from him again. It didn't matter to you since you hated him anyways
After 3 years of university you started to look for a job, but the reality hitted you at this point. You realized for the first time how hard it was to find a job without job experience. You searched every day and you had several job interviews. Suddenly one day you saw an job announcement where a CEO searches a personal secretary. So you decided to apply for it without a thought to search up who leads this company.
You made yourself ready in the morning and walked to the big company. You felt a little nervos as you arrive and waited. After a while you where the next in line to introduce yourself to the CEO. You put yourself together and enter the office but you froze as you saw Osamu Dazai. He was your past bully victim and you thought he would be rhater dead than being a well-known CEO.
You got hired by him and this surprised you. He kept his demenor calm and collected the whole time, but you didn't know where you got yourself into. Dazai was still mad at you that you always bullied him badly and he saw this as life time revenge he won't make your work easy for you and since you are his personal secretary he had more easy ways to bully you. He was about to turn your life into a living hell.
