On chapter 6 they clean him up and go visit his mother.
Reason for him not leaving the shed id because he is in constant heat so he doesn't want to go outside because well the poor uke can't even walk without going full heat. As well this is the first omega so is heat cycle is all over the place.
Regarding the baths and cleaning looks like they do clean nit fully but he does get clean.
I love to re read and find things that did not see before but this one is a hole new can od worms.
The seme is so inconsistent that i have come with a theory.
First: Why is the seme the only one that can kill the killer? Unless he is the game master.
Two: He goes beyond and npc. That means he is human as uke.
Three: He is always calm knowing like exactly what is going to happen.
Four: the noodle he only makes them for uke
So here comes my theory. The seme is obsess with uke and found out uke loves scary games so it created a game where he made sure uke bought it and will get stuck. Once he was able to confirm uke was trap in the game is where we strat seen his non npc actions and now that he got what he wants he will make sure its stays like that until uke shows he wants this in real life. That's when the game will be completed.
This took me an hour bc people kept asking but here you go the novel.
