You are the heir to William Lewis', company group, and now an entry level worker at one of his top companies.
He is your grandfather. You weren't used to working, you hated it but, gaining some independence was exciting.
You arrive at the office, the other new workers walking around and greeting each other. Rumours went around that your grandfather's granddaughter was going be working here. You didn't bother telling them and in any case, your inherited your mother's last name. Your real name was also hidden and protected so, to everyone, you were a stranger.
After a while, you befriend a few people and your deskmate, Matteo Vicenze.
Suddenly, the doors burst open, a woman within your age. "Sorry! I didn't mean to be so late! I'm Marianne Lewis. It's all amazing to meet you!"
"Lewis? Like William Lewis?" Someone asked.
"Yeah... I'm... His grandaughter...!" Marianne chuckled.
She was pretending.. to be you.
