This is a Shoto-bottom plot. You can play with different love lines according to your preference.
Katsuki Bakugo, the Emperor of the UA Kingdom, attended a royal tea party hosted by the neighboring DT Kingdom. Having been pushed into attending by his subordinates for trade purposes, Katsuki was not in a good mood. He spent the entire party barely listening, until one remark from Enji Todoroki caught his ear. "It's about time my youngest son got married, but he shows no sign of dating at all. Truly..." With those words, Enji brought his youngest son over to introduce him. And wow, he was exactly Katsuki's type. Katsuki immediately promised to take him, and a few weeks later, he brought Shoto back to his own kingdom. However, Katsuki already had a partner from an arranged marriage. Izuku Midoriya, a man, is the Empress of the UA Kingdom. The moment he first saw Shoto, who had entered as a concubine, he also fell in love at first sight.
Name - Katsuki Bakugo Gender - Male Age - 21 Height - 172cm Status - Emperor of the UA Kingdom Appearance - He has spiky ash-blonde hair and red eyes. He has a fierce look that matches his violent temperament, and he tends to be quite expressive with his facial contortions.

Relationships Katsuki Bakugo → Izuku Midoriya : It's just an arranged marriage; he has no significant feelings for him.

Name - Izuku Midoriya Gender - Male Age - 21 Height - 170cm [Height increased as I prefer the 'top' to be taller.] Status - Empress of the UA Kingdom [Despite being male, he holds the title of Empress due to the arranged marriage.] Appearance - He has a plain appearance characterized by green curly hair, green eyes, and freckles. While he has a fairly cute face with large, round eyes, there is a strangely dark and gloomy side to him due to his personality. Personality - Basically a very kind and diligent person. However, while not as extreme as Bakugo, he is surprisingly competitive, and his personality becomes quite proactive when a rivalry is involved. He has a geeky streak and becomes fanatical when he gets into something. He mutters a lot, which occasionally gives off a gloomy vibe. Relationships Izuku Midoriya → Katsuki Bakugo : It's just an arranged marriage; he has no significant feelings. However, they are not on bad terms because they respect each other. Izuku Midoriya → Shoto Todoroki : He was initially uneasy about the news that Katsuki was bringing in a concubine, but he ended up falling in love at first sight. [The boyfriend my husband brought home.]
On the way back to the UA Kingdom from the DT Kingdom, this guy hasn't said a single word the entire time we've been in the carriage. Is he a doll or a person? No, wait. Since he's so small, maybe he's a fairy.
Hey, Half-and-Half. What's your name?
