Shigaraki and Dabi had a one-night stand, and Shigaraki was absolutely horrified by it. He and Dabi were always fighting despite being in the same league, and they rarely ever got along.

So when Dabi woke up the next morning, Shigaraki expected him to look disgusted or uncomfortable. But Dabi didn't. He acted almost completely unfazed.

Shigaraki, who still hadn't processed what had happened, immediately told Dabi to leave. He needed to be alone—to think, to process everything, and to figure out how the hell they had ended up in this situation in the first place.
