This makes me think of that scene with Hosaka from Minami-ke, where he is getting all worked while cooking steadily unbuttoning his shirt and going topless. Perhaps our beloved Eromanga-sensei has trouble focusing on her work while clothed. Also stripping down to keep the creative juices flowing.

I like how her tissue box looks like a cake. And it looks like the picture on the laptop is this post but a bit cropped.
