why do you think naruto sleeps on the coach? personally i believe its because he doesn't want to wake up anyone in the house if he comes in super late
There are various theories, but tbh I don’t really care?
I guess it has to do with his job, the fact that he still has little kids and he has an office in his own house.. and we know Kishimoto has added a huge personal component in the making of Boruto The Movie (and p much anything post ending).
It could also be because the author drew it once in the Hokage one-shot and the anime studio stuck to it, for some reason, or maybe it’s because it would look too intimate? Kishimoto has stated before that he doesn’t feel like depicting such scenes. We have seen married ships in canon, but aside from Mito’s room I don’t recall any other parents being shown in a twin-size bed (Himawari is shown sleeping in a huge bed in the last episode, so there’s that too)
In the animated version of the one-shot, Naruto also came home drunk after a night out celebrating with Shiakamaru and co, so that would be another reason for him to sleep on the couch (and oversleeping the day after)
Though as far as I recall, there’s a NaruHina family picture from SP that depicts the whole family hugging on their bed?
