"Yu's...gone?" Diarmuid doesn't want to believe it, but he also knows that Shinju wouldn't lie about something like that. What he would lie about apparently? How he's feeling. Even Diarmuid can tell he's not okay. No one who has lost someone who they are good friends with here is okay right away.

"You don't have to hide how you are feeling to me. It hurts, right? And it's lonely not having him there..."

Diarmuid has lost a lot of friends since he arrived here. He knows too well how much it hurts.
