[It's difficult to say, though the assumption that Nagi is uncomfortable is probably true. Knowing that he and Omi have some prior history that he can't remember means that he's supposed to be reacting to him in a way that he's absolutely not doing...and that's not something Nagi knows how to field right now. Especially when he's sure that Omi's probably upset by the news.

Nagi stares at Omi for a long time before nodding once, looking up at the ceiling before letting his eyes close.]

Yeah. I should probably get some rest if my family is coming soon.

[Then, he pauses before adding.]

...I'm going to be here still for the weekend either way, I've been told.

[Meaning that Omi can return later, if he wishes.]
