It's always weird when Twitter manga get serialized. For some reason they seem to like reordering the chapters or edit them together in order to form a longer narrative.
Take the second chapter for example. It starts out with their first night, with the villainess clearly stating that she want to take her time. But it then cuts to a chapter that is clearly from much later and the heroine and villainess had already become intimate though the editing implies that it's the next day. It's really bizarre.
