My second light novel and another one shot really sold me on the genre. This is much more generally mature than the last one I read, though it is also still pretty chaste all things considered.
In an alternate world history, a basically English fop visits a famous witch shop for clues on his secret mission from the king. He meets the "Misfortune Devouring Witch"....granddaughter, as the original witch has recently passed of a semi-literal broken heart. The granddaughter is Japanese (basically) and immediately stands out in a world where boats are the only way to travel overseas. As a horrible tease, the lord is quite quickly taken with the witch who is awkward and inhospitable, but still making attempts. Soon he discovers her darkest secret, she is a vampire like her grandmother before her, and offers his blood. Little does he know (though she did) that binds them for life, as vampires can only feed off one person, who they love. Thankfully for our heroine, the hero decides by chapter 2 that he will marry her as soon as possible.
This is a love story between two people who can't help but be attracted to each other as much as they bounce off each other. The hero has some consent issues where he forces himself in the heroine's space that can be off putting to many, but is enjoyable to me. The heroine also very explicitly needs this, as she is tsundere and almost physically unable to communicate her needs. This is attributed to her vampire status, as they are not human and so do not feel human emotions the same way. They are devoted, passionate, awkward, and naturally isolated. The heroine comes off as someone with very real social anxiety and that the hero demands time with her is a slight blessing, because otherwise she could never let him in. He is very complimentary and doesn't wish to hide her away (all the time) but enjoys watching her bloom.
I will say that one of the reasons I love this romance so much is the hero's POV is very complicated. He is always half teasing with his emotions, even to himself, and it's pretty clear some of his love for the heroine is because he can exert so much power over her. This is not an exclusively social issue (in fact, she is from a very rich family and lives a comfortable life that she has no use for him in) but because he can cut through her walls so easily, and she is quickly flustered. However, in the way I always enjoy about those characters, in chasing her so avidly and forcing her in the corner, he, himself, is trapped in his need to chase or he'll be without her. To me, the unbalance is balanced by their equal need or each other.
The story is very serial, with most episodes standing apart and the romance being the thing that links them together. I would very much love to see this novel adapted into an anime or manga because I believe it would be beautiful and also, this is my trash so I want more of it.
If you don't like well done power imbalance and extra pushy romance heroes, please avoid, but if you do, please enjoy.
