When we first start watching, we again see the classic dynamic between Umaru and her Onii-chan.

But what makes this episode more emotive is that at the end we can see how deep Taihei loves her Little sister, and how much he cares about her, so that he could even think about improving her "Onii-chan" made lunch".

Pd: I rate visual in almost four, because the visual does not improve at some different level, but does not decline either.
