Thi story was awesome until you started introducing this elf girl that is obviously gonna be a harem at some point in the future. Now if it does not become a harem, then fans will feel like they're being NTR'ed due to the way she was intriduced. YOu also fell into the basic anime trope of being afraid of girls. The only guys who are afraid of not allowing a girl who is basically throwing herself at you is a guy who is concerned about the size of his tool. If a nice innocent girl throws herself at a religious person, by the third time of her saying 'let's take a bath together', the dude would be like 'okay, as long as you're aware of the decision you making, no problem'. Is the MC planning to be a virgin and 'B****' for the rest of his life?
I'm honestly loosing my patience with this. hes so weak mentally towards woman, its what I always see in harems and it pisses me off. like why is he being nice, maybe towards Ariel since he will get with her in the future but towards a stranger he should treat her as a friend and not just cause shes a woman. no backbone, if it wasn't cause I like the spells and stuff I would be gone I just hope it gets better
