Her future husband !

In the past, despite the hideous times during the Prime Circle incident, Eva thought to herself that she might be developing a strange crush on the mysterious man who saved her. 

In the midst of confusion, she couldn't see his face or determine his age, but she confessed her newfound feelings to her brother and others.

She never even liked a man this way but she said she loved him to Xylon as if it was true and sincere.

" Xylon was right…I am just so stupid to even think that this guy was different" she thought .

As she began to walk away, attempting to distance herself from the unsettling emotions, X quickly caught up with her. 

Desperation colored his words as he pleaded, "Hey, Eva, don't leave, not now."

The fog of confusion lifted the moment she knew about the harem rule, and Eva was left with a stark realization – she was utterly disgusted by him.
