Hello,
I’m looking for a yaoi manga/manhwa/webtoon, but I can’t remember the title or the cover...
It is set in a medieval European-style world, with omegaverse elements (or something similar involving pheromones).
The story is mainly told from the perspective of a young man, likely a prince, who agrees to a political marriage for the sake of his kingdom. However, his future husband is a much older man from an enemy kingdom. This man is an extremely powerful alpha, holding a high-ranking position (duke, archduke, or army general), and he is feared by everyone. I remember that the old guy moves into the other kingdomand leave his responsabilities to be with the young man.
The husband is significantly older (at least in his 50s, while the protagonist is in his 20/30s), with white hair and possibly a white beard. His appearance clearly shows his age.
The content is adult (18+), and possibly black and white.
I think it's not a very well-known work, and I am not even sure it is a “pure” omegaverse story.
I believe I read it online, but I don’t remember the platform, and it was quite a while ago, but i would really like to read it again, as the trops with older man like this are quite rare.
If anyone recognizes this title, I would really appreciate the help!
