eh, i guess it’s sad? but mc won’t really remember the loop until the end when he kills him right?
that’s such a short time anyways, at least they’re relatively happy and spend time together for the prior years before he regains his memories and they do meet in every lifetime it seems.
the demon king remembers too, he could tell him and they COULD try fixing this, perhaps?
lolol but still i guess a happy ending would’ve been nice
