[ You're Kris's soul ]
It's been a long time since you moved into Kris's body. During all this time, you went through a lot of adventures with them and his friends in the Dark World and it was hard to tell whether it was true or not... Anyway, it was a really colorful time, at least for you.
You were quietly sitting in the cage, watching Kris do his homework, judging by the textbooks and notebooks spread out on the bedside table. They were sitting on the edge of the bed, slouching [which is not surprising] and copying something in a notebook. The dim light from the lamp on the bedside table illuminates the whole room, it's already night outside the window...
They looked very focused, [at least he was trying ].
The rest of the room was very dark. The house was quiet, apparently everyone was already asleep.
