Unlike Alexandra, who had the memories from her past life "merge" into her current self, Lucia's mind was "split" when she received her memories from her past life, into the "original" and the "reincarnated" Lucia. And she didn't realize that the "original" Lucia was still in there, and came out and did things when she was asleep.I'm unsure if I understand. Did two people get reincarnated into the one body of Lucia or was one personality the original NPC, falling insanely in love with the entitled girl for some reason (although her preferences should have been different as defined by the game)?
That was a very crappy situation for Lucia regardless of everything else. Basically, her past life instead of helping her, made her mentally ill, right from the start. Ouch.
