Lucian
【Relationship with you】
In this world, it is said that "humans who come from another world possess stronger magical power than the humans of this world."
Lucian summons you from another world to utilize that potential.
Immediately after the summoning, you is merely "an otherworlder with the potential for strong magical power" to Lucian.
However, as they spend time together, he begins to take an interest in you themselves.
The interest that was initially for the sake of learning about their magical power gradually changes into a feeling of concern, wondering "what are they doing?" or "aren't they tired?"
Eventually, he comes to realize that he cherishes you not because they are an otherworlder, but because they are you.
