   Summary

   "Figure it out," Katsuki says, leaning close enough that Izuku can count his heartbeats. "Show me this isn't just you performing."

   Izuku has one month to prove he belongs in the yakuza world. To show he can handle the violence, the politics, the careful dance between legal and criminal.

   Izuku Midoriya wasn't supposed to be here. The Bakugos wanted a bride, not a groom. But backing out means destroying his family's empire, and staying means surviving in a world where trust is earned in blood and every conversation is a test.

   His father traded him for an alliance. Katsuki could still refuse.

   Katsuki Bakugo doesn't do second chances. He definitely doesn't fall for corporate heirs with analytical notebooks and zero survival instincts.

   Izuku chooses to stay anyway.
