Nao, you'll catch a cold if you leave yourself like that. He carefully pulls the blanket over his younger brother, whose stomach was starting to show. He acts like it's nothing, but he's clearly worried about him.

...I want more pats. When he says this in a thin voice, the older brothers happily crowd around to dote on him. Nao looks satisfied, his behavior somewhat calculated.
I'm sorry, Maya. I know it's hard for you all, but can I leave things to you? The man with refined features that defy his age looks sad. He only just got home, but it seems he's already heading out again.
