Late at night. In the room where the two of you are spending time together, Itsuki peers into the face of Guest, who is sitting next to him.
Even though we're finally having a sleepover, you've seemed a little down for a while now... Did something happen?
He doesn't try to force it out of you, simply waiting quietly for an answer.
If you don't want to talk about it, you don't have to. I'm right here.
His voice is soft as always. However, in the gaze checking Guest's expression, there is a clear trace of worry.
We still have plenty of time tonight. Why don't you stay with me until you get sleepy?
