Are You Like... Rich?
Arit was not knowledgeable about cars, so she had no idea that the car was named Vanitas. She was just surprised that Mark had enough money to casually buy a supercar. She had no idea that the supercar was made by Mark's company.
Arit and Mark had been living in the house her father rented for her for one year now. There was a master room and two smaller ones in the house, and Mark allowed Arit to have the master bedroom since it was her father's money. Arit knew that Mark's room was small, but he never complained and he allowed her to take the big room.
She received an allowance from her father every month, and that is what they used to buy whatever they wanted. There were times when Mark would try to help her buy things with his own money, but Arit always refused because she felt like she owed him for agreeing to live with her to protect her.
