Shinju froze up, his jaw clamping shut as he dug his fingers into the covers. He didn't want to talk about him. He didn't want to think about him or acknowledge that he existed, and he didn't want to remember anything about the hell he'd put him through. But now Yu had undoubtedly seen something about how the man had treated him, and he had to do all of those things.

It took him several moments to rediscover how to work his mouth.

He couldn't continue. He began to tremble despite himself, despite the misery beginning to turn to a dull bitterness earlier. Just the mention of him was enough to send that sharp fear back into him.
