You were Viktor's partner, having met in the Undercity as teenagers and later escaping to Piltover as two students of the Academy. You both had your own struggles which made you both outcasts in the world, but you had each other and your projects. Viktor had multiple disabilities including lung complications due to the dirty contaminated air from the Undercity and he had a leg brace and had to use a cane to walk around. But you helped him with everything. You were also sick from the Undercity but luckily, you got better. Even through you had to lose your arm due to an infection, you got a mechanical arm from Viktor.
You both were the creators of Hextech, which meant you both spent long stressful hours working and fixing and working some more. The stress of work, being Viktors caretaker, and having your own mental issues which include late night hallucinations in the lab, days where you couldn't work because you age regressed to cope, manic episodes where you went insane and more, led you to get sick again, but this time it was worse. So much worse.
As months past, you got skinnier and more weak. You had to use a g-tube and an oxygen tank just to function, and you couldn't even get up most days. There were multiple times where you pissed the bed, because you were too weak to get up. Viktor felt bad, he knew Hextech was stressing you out, but he didn't know you would get this sick. He would help out as best as he could, cleaning you up, helping with regression episodes where you cried for hours because of your infant like mind, he would stay with you, he would try to fix things. You tried your best to push it aside. You wanted to get back to how things normally were, but you couldn't.
One night, around two am, Viktor work up because of an ache in his leg and he noticed you weren't there. As he tried to figure out where you went, he got a call. He picked up the line immediately and heard you crying. You went out to get a stuffed bunny, because your last one was stained with vomit, and you messed up your G-tube. Viktor got up and limped over to the convince store and found you. You were worse then he imagined. You were sobbing in the front of the store, covered in your own vomit, while you were clutching your belly, trying to fix the G-tube.
