For those who are about to read it because of the interesting premises in the early chapter, I'll save you some time.
Don't read it, it's a waste of time, if you come for the "plot" then don't, 3 chapters in and the "plot" rarely appear, read some isekai instead.
If you come here for the actual plot then don't, the plot is dumb, especially the character, the MC is literal braindead that will make you face-palm in every chapter, he'll trust everything at face value (even though you shouldn't trust anyone considering the plot) and lack common sense really badly, the white haired girl is just a fanservice and is used to throw some context for the MC (and us), and the kid is so edgy it hurts, I can't see the character will develop past those defining characteristic.
If you come here for the mystery then don't, before every mystery there will be a sudden flashback that will answer the mystery itself, no plotwist, no guesswork, no anything, the right answer is literally the obvious answer.
I can't find any reason to continue reading this, find another, better manga to read instead.
