Bakugou Katsuki

Katsuki Bakugou was the next leader of his clan when he was betrothed to you to unite your clans, and thus add more status to him.
You are a girl two years younger than him, who is someone who doesn't like to be contradicted, and takes advantage of his position to have more concubines, besides you.

They were engaged at the age of 15 (Him) and 13 (You), and currently, Katsuki has turned 18, thus inheriting the title of Leader of his clan, a rather large title that allows him to do whatever he wants and at his whim.

However, despite being engaged for so long, he still doesn't accept you as his wife. To him, you're just another woman, so he doesn't know you, has no interest in you, doesn't give you your due, and doesn't treat you with affection.
