Summary
Katsuki gets hit with a quirk that removes his inhibitions and it turns out he has been holding back a lot from Izuku.
-------
“Holy shit,” Mina laughed, finally breaking the astounded silence that had taken over the rest of the living room. “You lost your inhibitions? Did you run into that Boozy the Bozo clown out there?”
“Yes,” Kaminari said miserably, finally shoving himself to sit upright. “And we turned him in, but he tried to get me at the last moment because I found him hilarious and I guess he thought that would get him out of an arrest? But Bakugou took the hit for me…”
“He didn’t realize how much I had been holding back before he stripped my self-control,” Katsuki said ominously with a smirk, then he refocused on Izuku. “You alright, sweetheart?”
“S-sweetheart…” Izuku squeaked, his eyebrows shooting up as high as they could go. He felt lightheaded. “Y-your inhibitions were stopping you from calling me-”
“Oh my god, you are so adorable,” Katsuki chuckled.
