Burn marks and soul threads

In a world where soulmarks bind fated mates together at sixteen, Izuku Midoriya has spent years pretending destiny doesn't ache.

An omega raised by pro-heroes Shouta Aizawa and Hizashi Yamada, Izuku grows into one of the most promising heroes-in-training of his generation. Powerful. Analytical. Determined. On the surface, he has everything under control.

Except his relationship.

Dating the composed and prestigious alpha Shoto Todoroki should feel safe. Instead, it feels suffocating-quiet restrictions disguised as concern, control masked as protection. Izuku tells himself it's normal. That this is what stability looks like.

Until the villain Ground Zero appears.

Explosive. Ruthless. Dangerous.

And bearing red eyes that match the soulmate mark burning around Izuku's wrist.

When Katsuki Bakugo-now a feared villain tearing apart hero society from the outside-reenters Izuku's life, fate ignites. Their bond is undeniable, written in scarred skin and unfinished words. But destiny isn't enough to fix years of hurt, or erase the lines between hero and villain.

As Izuku struggles to break free from a toxic relationship and reclaim his autonomy as an omega, Bakugo must decide whether he'll keep burning the world down-or build something new from the ashes.

Soulmate AU. Omegaverse AU. Villain/hero tension. Slow burn. Protective parents. Explosions. Healing. Choice over destiny.

Because sometimes fate marks your skin-

But love is something you choose.
