Chill people everthing takes time. You can't expect people to recover from their traumas that fast, nor you expect them to trust others wholeheartedly in a short span of time just because they changed recently. If you truly like this manga, then you should look at the perspective of the characters and relate to their experiences as real as possible. Do not selfishly wish for this and that just because it satisfies you that much.
I dont know goddammit this may seem really really twisted but i want more of dion and roxanne scenes like so bad.
Omg yasssss
