Foreknowledge of twists should not hinder your enjoyment of a work, if said work is written well enough. Or in other words, if the only thing a story has going for it is the twist, then it is not much of a story at all. Personally I rather not delve into spoilers before reading something, but I can understand people who do not wish to read certain things by accident.
At any rate if the husband in this story turns out to be yet another villainous asshole, then this manga will go straight to the trash heap with the rest of them.
