From Boys On Boys Love:

Once every hundred years a bride is chosen to be sacrificed to god. This time though, Will was chosen.

Aoba Koo works part time at a cafe at the capital of the demon world. Very cute and very funny.

Tsubaki is her school's most proficient student, is polite, and is absolutely good at everything, and little by little, people are hailing her to be the school's queen.... And she absolutely despises that. She quietly admits to herself that being a "perfect student" is not her real personality, but a clever ruse to become a more likable person.

She is, however, still not able to interact normally with students and thus is dissatisfied--a fact that prompts her to follow the advice of a magazine on finding happiness: the magazine states that by meeting your doppelganger, you will achieve long-lasting happiness. Determined, Tsubaki follows the instructions in the magazine and opens up the "door" that will allow her to meet her doppelganger....

...And the one she meets at the other side, "the other world" is not who she was expecting.... Well, it is someone who is strangely identical to her when it comes down to it, but it is also essentially different.
