Ore dake no Tsugai ni Nare yo

Kirishima and Bakugou are dating. Mina and Uraraka lend Kirishima some BL manga, specifically Omegaverse. Kirishima goes to a bookstore to find more and meets the author, who asks him to help her with her next work by acting out an Omegaverse scenario with Bakugou. Kirishima agrees and takes a drug that makes him go into heat. Bakugou takes care of him, and they have sex. Kirishima wakes up from what he thinks is a dream about having sex with Bakugou. He messages the author thanking her for the dream, but later at school, he sees a bite mark on Bakugou's neck, realizing it wasn't a dream. The author replies that she didn't use her quirk.
