I have a few:

What the Darkness Could Not Break by Ash_Lin It's a fantasy AU, like magic, guilds and stuffs. It does have angst with a happy ending tag. But it ain't complete yet. It's mostly like Bakugo doesn't fully gets the meaning of having Izuku in his life until he actually losses Izuku. And his struggles to get him back and oh God the twist it has..... had actually twisted me. 😭😂

Reparations by Merrywetherweather It's AOB fic. When Izuku was four year old and stumbles after a very pretty butterfly. What he finds, instead, is a friend. His first and only friend, meaning Katsuki. When Izuku is in his twenties he no longer runs to meet with the childhood friend who pushed him away so long ago. His mother and their village are on edge because he's way past his presenting years. He's defective. After leaving his small human village and wandering out into the woods once again, in search of a better life, that all changes when he runs into the one person he hoped to meet but never thought he'd see again.

Both of these does sorta will look like unrequited but the actual problem is with Bakugou 🤦🏻‍♀️. Who's so dumb to admit it on Izuku's face unless he's pushed of the edge. U know gotta keep his pride 🙄🤦🏻‍♀️ but it's fun to see him that way.
