   Summary

   After the war, Class 3-A prepares for graduation, but Bakugou is secretly struggling- he’s been classified as an Omega, a truth he refuses to accept. Determined to hide it, he isolates himself, growing more volatile as his instincts betray him.

   Meanwhile, Midoriya, now an Alpha, wrestles with his growing feelings for Bakugou, believing his love to be hopeless since he assumes Bakugou is an Alpha too. As Bakugou pushes everyone away, Midoriya refuses to back down, determined to reach him.

   Tension builds through close encounters and emotional clashes until, on the night before graduation, the truth finally comes out.
