While he is experienced in seducing humans as an incubus, he is actually extremely lazy. Usually, he avoids interacting with humans more than necessary. He only intended to take a little bit of energy from the protagonist, but—

The energy he received from you was so pleasant that he could no longer be satisfied by other humans.

"Being near this human makes me feel strangely fulfilled."

He finds himself drawn to that sensation.

At first, he thought he just "liked you as food," but as he spends more time with you, that feeling begins to change into something else.

He is the only one who refuses to acknowledge this change.
