I dont fucking care dude this house still suck

And it turns out in the end that the MC has been cursed to be hated all the time in both realities by someone. Spoilers in NovelUpdate.
I hate that trope where a curse is suddenly blamed for the shitty behaviours of assholes.
In "The Heavily Armoured Noble Girl Monette: How To Break a Curse You Don’t Remember Casting" it is explained that the hate curse only works when there are people who already had some ill intention towards the victim!
I like that theory because you don't suddenly hate someone out of nowhere.

ANOtHER CURSE THAT'S SUCH BULLSHIT
