Another punchline-less comic.

Not to make light of Murasa's condition but I suspect based on this and the previous story the artist is trying to tell serious stories in a format that doesn't particularly lend itself to them.

Or the joke is, now that she's being left alone to go back to sleep she can't.

'Sides, it's a slice of life comic. Not a gag comic per se.

Poor Murasa, looks really uncomfortable! Been some time since I last had a high fever and can't say I'd miss it.

she isn't, you can see her wearing a new shirt on the first panel.
