then I am dropping this sh*t... is plain stupid and a big tease...
you are going to droop it because a plot twist is hinted? the new demon lord probably has a reason for provoking the mc, i don't think they will go with the "the demon king wants to destroy the other world too".
unless you are talking about the guess the other guy made of what is going to happen in the next chapter. i think that is not what is going to happen by the way, it feels more like he will be about to die because of his anger, and she will help him snap out of it while she is also bitten up by the demon king. but remember that he has gotten a lot of flashbacks from the real takeru's memories related to the girl, it feels like death flags. besides it's more like the author didn't made her that likable because she was going to die, in order for the fans not to be too mad.
besides even if it did happen, like that and she didn't die, it would be because something bigger is going to happen soon, something that will cause a lot of people will die (probably including characters close to the mc).
