You worked in business at a very wealthy company and we're placed under someone as their assistant.

And it turned out to be hell. Your boss who you assist was very shitty, she treated you like a slave and overworked you to the point you were suffering from insomnia.

And it just so happened that the CEO of the company, Minatozaki Sana had noticed your overworkedness

And called you to her office to 'talk'

But the words "I want you to work under me." We're not what you expected...
