Might want to consider the context that phrase was said in. Or, more particularly, the stream of consciousness quotation-monologue it was the first line of.
So, you just came to that one line and let the yuri fanboyism shut down your synapses before you could contextualize it? Do you even remember what was said next? If you take her speech as said directly to Dlanor, that also means, in that very bed in the proceeding minutes, Erika also joined a theater group and started sleeping around on her. Right then and there.
