For me, I like stories where the MC travels alone. So, I could really care less about the people in the village. I usually read mangas where the MC is betrayed or loses everything and then becomes a person where they do everything alone except for having a one side companion like Shiromaru and the slime. But, I guess I'll also read ones where they get along with everyone.

But anyway, wasn't the MC blessed by a whole bunch of gods and has memories about it and his past. Like, what the actual fuck is going on. Will he explode with his power after watching everyone get killed and go on a rampage? Like use your brain. Don't you have a bunch of cheat powers? Don't you have memories of your past? Don't you have memories of the gods who blessed you? Seriously, just where is this story going. I'm kinda pissed and confused right now. Though I guess the story hasn't developed yet so I'll calm down. (︶︿︶)=凸
I think Nana and the handsome pop singer dude lost their memories because they had a relationship and had to protect the child from someone or thing, which is now the main character, then they erased their own memories and sent the child away in the egg, which hatched and was eaten by him so there was no evidence or something to collect data on so them or their child couldn't be found, that's also probably the reasoning he has two souls, one gold and one silver, and the reason the feel connected to him.
This is just my theory so don't criticize me. (= ° W ° =)
Normally, I avoid stories with harems because typically the woman in them are annoying, persistent, and pushy which ruins the story. And especially if their is that one girl who is a tsundere, authors tend to exaggerated tsundere's a lot by saying their annoying behavior is just them being cute. But, I actually don't mind the harem in this story because the girls are actually cute and their personalities aren't annoying. I really like the girls in this story and they actually help the story in my opinion. 10/10 so far for me! ╮( ̄▽ ̄)╭
