It's like 'Orenchi ni Kita Onna Kishi to Inakagurashi Surukotoninatta Ken' and 'Welcome to Japan, Ms. Elf' had a disabled child.
Plot and character development are sacrificed too often for fan service. There's some ecchi (Somehow, her nipples are constantly erect), but it's not as blatant as many ecchi manga. There's some comedy, but it's subtle. There's some drama, but it doesn't push the characters forward in their development. The elf character is exceptionally bland. The MC is super-beta. The few other supporting characters are paper-thin throwaways.
The pacing also feels off. The author slow plays some inane plot points while other, more important plot elements begin and end way too quickly. That said, the author isn't completely incompetent. There's some foreshadowing in the mix about the reason the MC is as beta as he is. And, there are kernels of a good story hidden behind the tepid fan service and half-hearted comedy. It's far from the worst manga I've ever read, but I'm on the fence about continuing to read anymore.
I've read manga that are far worse with far better ratings. If that counts for anything.
