The point is that Fuuko and Grune-san were out of the way. You never said anything about how far out of the way Fuuko and Grune-san had to go!

[So their being where they are is totally justified okay.]

Fuuko thinks the room would look fine being painted pale yellow, or green. [So either the colour the room was before or a colour she likes.] However Fuuko is open to both of your opinions on what colour the room should be.
