    Summary

    Izuku's omega believes it was rejected by the alpha it imprinted on when he first presented in middle school. An alpha that fucking hates him.

    And to make matters worse, he has a rare condition where his body builds up antibodies to suppressants and they won't work on him. So he spends every heat in excruciating pain, bordering on Heat Sickness.

     

    -or-

     

    It's for the best that Support Engineer Izuku hasn't seen the now Pro-Hero Dynamight since middle school.

    Until Katsuki walks into Izuku's lab and his life, forcing him to confront his feelings head-on.

    Summary

    Summary

    Katsuki slid a piece of paper across the desk to Izuku.

    “Here,” he said.

    Izuku took the paper, scrutinizing it, before saying, “Uh, I don’t really know what I’m looking at?”

    Katsuki stared him dead in the eyes, expression serious as he stated, “It’s my heart.”

    Well, that much seemed true. The paper, a thick glossy sheet, showed what was visibly an x-ray of someone’s chest, bones glowing white around an indistinct blob that lay where Izuku knew a heart would go. The question was less what? and more why?

    -or-

    Izuku Midoriya is given Katsuki Bakugou's heart.
