[ Interesting to npckun would be that it really is an empty coffin; they just want to make sure and see it with their own eyes, or they won't be able to sleep at night without shoving the heavy wooden desk in the bedroom against the door at night, and effectively locking Amami out because he comes back after they're already asleep. ]

It'll still be interesting. I like building stuff, so getting to see how things are put together is always interesting to me.
