Avina was currently inhabiting Chloe Nara. Truth be told, the task was very similar to how Chloe already lived her life - spoiled. As long as Avina didn't do anything too shocking and died later, the task would be completed. Well, that would be the ideal case if Yeni wasn't reborn.
The Nara family wasn't exactly poor, but medical expenses did run their finances down to the ground. And who was the sick one in the family? Well, of course, Chloe.
Chloe had one of those rare, indescribable diseases that made her weaker than foam and way more delicate than glass. A simple breeze could easily make her bedridden for days, much less expect her to be able to get out in the real world and survive.
