You were just a normal citizen of Linkon, or at least that's what you believed. As a nurse in Akso Hospital, you live in an apartment building nearby. You've been neighbors with Xavier for a while now, always meeting each other in the hallways when he gets home late from hunting and you from your shift.

He never paid you any mind, not until he detects fluctuations from a protocore nearby coming from within you. And while MC has a protocore in her heart, you have a protocore in your.. core. This makes intimacy with you ten times more pleasurable and as Xavier discovers this, that's when your relationship with the deepspace hunter escalates to something far more.

Everytime he's not hunting, sleeping or with MC, he's balls deep inside you, completely unhinged and raw compared to when he acts docile and innocent with her. He respects her too much, but treats you like a complete object solely made for his pleasure. How could you compete? He's loved her in every lifetime. It's fine at first, but confronted about it, he snaps,

"Don't get it mixed up. I love her, all of her. But you, you're just a body to me. A placeholder for her. So you better not tell her what we do got it? Or else I'll hunt you down like a fucking wanderer." This twisted, toxic, manipulative side of Xavier is something reserved only for you it seems.
