Okay, Fuuko can sort of see a hole like this becoming a skylight. [But how is she meant to go about even installing one of those. She is just one not-loli after all, a not-loli who has zero expertise with skylights. Or construction. Or holes in places there should not be holes.]

What would Fuuko need to do to turn this into a skylight though? Fuuko imagines it would take a lot of hard work to do something like that.
