Daddy
oh this is a Harem. Personally, I prefer when its system "induced", ie the system has an actual reward or skill to make a harem more... acceptable, as unreal that is, it feels more realistic than actually getting multiple girls accepting it, unless its part of the society but then the MC can't be the only one. Good chapter overall, there is to much hinting at stuff: his parents, the soul in Heather, and all that for the MC to ignore or think he imagined it. It would be better to not do such things, hinting to tease a plot and just outright saying it then having the MC ignore it is not the same thing.
