What I'm saying is it will be much better if he's focus on finding his sister than being a naive one he could be much faster leveling up than helping those girls. And no harem there are already too many indicators that it has so if you want read it but me I'll drop it cause it's been diverting too much.

Dropped at chap 51 I like the mc and how it goes and OP mc with the mindset of his goal but these girls always close to him and leeching off experience points without doing anything and leveling up using the mc and not doing the hard work for themselves especially that pink hair. I get that the mc didn't mind and just focusing in his goal finding his sister but he's too naive that he didn't notice that most of them are just using him to level up.
