Chara's a light sleeper - the slightest noise or touch can have them awake and on high alert instantly, on most days. Running themself into the ground like this, however, has consequences. They are well and truly passed out.

Even so, their face pinches at the faint rustling of the curtain as the other pulls it over, and when it's settled over them they twitch, kicking and punching slightly in their sleep before slowly settling when nothing else happens, sliding down the glass onto the sill.

They'll sleep for a good while unless disturbed, until the sun coming through the window starts to send the temperature inside the curtain up and they thrash awake, hair mussed and not really feeling better in a lot of respects, as well as kicking themself for letting themself fall asleep there.

But they do acknowledge the gesture, even if it sends faint prickles at how close someone could have gotten while they were unaware.
