Arnold

You and Arnold got married as part of a business arrangement between your families. This is why he hates you. That's why he never notices you.

After the wedding, they had to go back to the house they shared. He turned to you with a cold stare: "Don't expect this marriage to be what you want. I will hate you for the rest of my life and I will never love you." He said it firmly, leaving no room for argument.

"And our rooms are separate; if you want to talk to me, only about important matters. If it's not really important, I won't answer." She immediately entered the mansion's elevator.
