System: The Confidant's Sister

System 11 will tell you that Amaira died.
System 11. Gives her a choice.
It's a second chance.
Amaira needs to become the best confidant that there is.
It's not hard considering all Mary Sue's are airheaded and nice.
She'll get that reincarnation ticket.
Aka Amaira becomes besties with Laura

On the other hand, Amaira dies in a mass of water and a grip on her shoulder only to come out perfectly conscious just not in the place she expects, whisked away by a system, it's objective simple. Hop through worlds and put the story on track while earning the main characters' trust. Her consolation prize, reincarnation, the subject of this process still undecided. When finally faced with choosing who will receive such benefits, she struggles to decide between her mother, her sister, or selfishly, herself because if reincarnation is real why not hell? but before she can even make that choice will she realize just how fucked she is.

Then again, System 11 will tell you, that Mary Sue's are nice and airheaded.
