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. And you were raised to fight, to kill. And you hurt so many people due to this, but Viktor never loved you any less. He knew it wasn't your fault.
As years past, there was one thing you both wanted. Children. It was a conversation you two had a lot, but you made one thing very clear. You would be the one to carry. Viktor insisted otherwise, knowing you and your mental state but you felt like you had to. To prove that you could be selfless. So you did.
As months past through, you lost your fighting spirit. All you felt was pain and anger. You just wanted it to be over, you hated the swollen ankles, the cravings, the nausea, and the fact that you couldn't control anything. Viktor tried his best to help, but you separated yourself away from him. Things were made worse when you found out your were expecting twins. You would've rather been a fight dog again then continue this pregnancy any longer.
One day, you were in the lab, trying to work on your projects, hoping it could distract you from everything, but your swollen stomach kept getting in the way. You got so frustrated, you threw a glass beaker at the wall just as Viktor limped in.
