Notes of Regret // Dekubaku

Izuku had come a long way from the stick-thin, weak pup he used to be - it had been a path filled with blood and death and pain but he was finally ready, ready to get close to him, to put his plans into motion and ruin him once and for all.

But what happens when Katsuki doesn't turn out to be who he used to be?

The omega was different, scared and anxious and feeble, so unlike the boy that used to torment Izuku.
Hatred and infatuation get mixed together until all Izuku can think about is caramel and fire and red, red, red.

Or:

Alpha Izuku creates a plan to get revenge on Omega Katsuki for the way he treated him in Middle School, but Katsuki isn't the violent person he once was, now he is filled with nothing but fear and self-hatred and regret.
