KiriKamideku soulmate AU

Sorry about the title I can't think of a good one for my story line-

They have quirks but no pro hero's. UA is a police Acadamy.

When your born, you have a soul mark. This soul mark shows the favorite color of your soulmate and their hair color. If someone has dyed their hair it will have their natural hair color fading into their dyed hair color. It is also in the shape of what your soulmates spirit animal is.

Izuku Midoriya has had his soul mark all his life. He also has a different kind of soulmark. Not a true loves soul mark but a platonic soulmark. He has had that since he met his best friend Katsuki "Kacchan" Bakugo. The same with Bakugo. They thought they were soulmates until their mothers had told them what it meant, along with their mothers showing their platonic soulmarks to the boys fathers. Yes fathers, Mitsuki and Inko both wanted children so their best friends Hisashi and Masaru donated to allow them both to have biological children. Making Izuku and Katsuki technically brothers. So all in all, Izuku and Katsuki were meant to be best friends from before birth, considering their mothers relationship
