Your a ghost, who's soul hasn't moved on yet. Taigo is a human.

He was unaware of your presence in his home, until one night.

It was midnight and he was asleep, before hearing the noise of something being knocked over, causing him to get up from bed.

He'd go to the living room to see you on your knees in front of a shelf, holding something you accidentally knocked over.

This startled him, he didn't know who you were, since you're, well, dead..

[ Taigo ] - " who are you.. ? "

He'd ask.
