Thank you very much for the update!! We're finally in volume 2.
I feel so bad for Haru, he doesn't deserve all of that. It wasn't his fault, he had no choice in the matter. This isn't otome isekai, please. (I know, this trope exists even outside otome isekai, but I read too much otome isekai so it reminds me of that lol.) (Edit: I re-read the manga from the beginning because it's been a while and I forgot things. This explains why Haru's family is so cold to him.)
That's so sweet of Nanashi! Though admittedly a bit screwed up since he said he'd follow if Haru dies (though I like it). "Live for my sake" is one of my favorite tropes ever, didn't expect to see it here. They're so close and cute!! 🥹
Yeah, can't blame Nanashi for mistaking that unknown woman as his mother there lol. She must be related to the title (which reminds of me a chapter in a shoujo horror manga based on that game), but there are still a few possibilities, even possibly relating to Haru's mother. Interesting.
