Ngl, I got jebaited a bit: first half of this chapter, I started thinking that the system wanted to rehabilitate her so that she could live a normal life once she got back to her world...I mean, just look at her, unable to remember her family, unable to trust others, unable to almost understand others...she'd have a lot of problems if she got back as of now.
But then, the system got bored when Yiyoung decided to not "fight" anymore, gave her an ultimatum and even blocked martial gramp for a couple of days....well, I kinda forgot that "owner of the tower" also ended up here and probably overtook some things.
You know, if I was in her position I'd bring up to the system how close I would be to destroying the world myself with how pushy, unfair, and uncaring the system was being. I mean, she is or at least knows how to quickly become the most powerful being in the world, whats a few (or all) devastatingly destroyed countries in comparison to making a point to the system?
Could happen, but we don't know if sealing the constellations will affect Yiyoung or if the system can give her conditions like "do x or die" or some bullcrap.
