No idea, this isn't even cute [in the point of being cute because of the the things happening, not because of the characters being "cute].
I think we need more simplistic/ non-stereotype heroines who are by default not beautiful, but I don't agree with these manga trying to appeal the same way with the same tropes regurgigated again and again. It makes me feel like a cow eating grass and re-digesting the same grass again and again and again.
First it was yankees[Onidere,Koisuru Yankee Girl], then it was shy girls [Komi-san wa Komyushou desu, Hakoiri Drops, Aharen-san wa Hakarenai] and now they even infiltrated the fantasy knights to resell the same tropes.
Why can't the characters be more individually appealing like in Kono Subarashiki Sekai ni Shukufuku Wo, combined with a "not bishoujo"-design?
Also, the main character is just a shallow fetishist. He knows nothing about the female lead and is just all over her "unsightly" body [as if scars are so unsightly, it's not as if she lost parts of her body;
how about having only half of an arm, half or no ears, missing a lot of teeth?]
The author isn't even trying with this.
The main character isn't trying to learn anything about his loved knight, he's just a creepy stalker with a fetish for scars and abs.
If you like it, good for you. Doesn't change the fact that this is badly written and story-boarded.
