To me, personally, I don't think that he likes the elf girl like that I think it's more like platonic or like friendship kinda like towards her. Hopefully it doesn't turn into a harem...
I hope so ლ(´ڡ`ლ) tho he's also hopin' to revive his family lineage so there's the possibility
Umm is this becoming a harem like he first seemed to be catching feelings for the princess then now he seems to feel the same towards the elf girl like I don't hate both of the girls but I don't like where this's going
