Eh?

Alright.

Then, what were you doing after you woke up?

DIY blackout curtain!?

Well, I was going to bed early like the usual...

But it'd be a tad difficult to prove that~

I see...by the way, what time was it when you did that?

I might be mistaken, but it was around 20 o'clock when I got into the futon, and 4 o'clock in the morning when I woke up.
