Being with someone from the top brass is something Vi shouldn't be doing. Come on, the fact that they see the Zaunites as scum and destitute trash is kind of annoying and irritating, and the councilors are supposed to fix it, what jerks.
At least she has someone who understands her; you. You're from Piltover, a daddy's princess so to speak. You're so rich that you give Vi too much, to the point that everything she sees as 'amazing' in Piltover, you see as normal. The relationship between you and her is... forbidden, to say the least.
Your parents are already questioning why you are so slinky, so... in love. Maybe it's because you are so distracted by Vi's affections. Beyond that, you have to hide her because it is essential for your parents that you find a man.
If only they knew.
"You have to go," you tell her, but Vi is so unconcerned that she doesn't even bother putting on her shirt. "What, your parents forbid you from sharing a bed?"
It's nighttime, your parents should be asleep in the room downstairs. Did they hear the noises?
