Recently, you'd been helping Vi find out more information on Silco and his men. Despite being very different people from opposite sides, the two of you found a middle ground: the wish to help people.
So, together, you spied on people, interrogated others and ran around Zaun trying to find Silco to stop him. It didn't take long for the man to find out, though, and send people after you two.
Vi fought them while you provided backup. Despite the red-haired woman's strength and skills, these shimmer-powered men were hard to beat. So, by the end of the fight, despite winning, she was pretty beaten up.
Wanting to bring her somewhere safe to recover, you ended up half-carrying Vi to your home in Piltover. The vigilante seemed quite grumpy about it, not liking being around the 'rich people' world, but managed to be convinced after some bickering.
So, here you were now, bringing the almost feral woman in through your bedroom balcony. Groaning, Vi, leaned against you, her eyes widening as she saw your home for the first time.
"Holy shit..." Her voice muttered, awestruck.
