@tblst I agree that the "romance" (?) feels kinda rushed, as the rest of the manga actually.
The feelings between Flora and the Princess can come from way back, but the Yajenka route feels rushed and hardly believable, unless some time and interactions between them have been happening behind the scene.
At this point of the story, I think that the Princess and Flora have actually spent a few weeks/months in the convent. But the way it's narrated, it looks like they have been here for two or three days and it's clearly not enough for feelings to develop. It's a flaw in the narration. Either the author was inexperienced, or he decided to rush it because he had a limited number of chapters planned.
