I wonder if the manga will cover the events of the sequel book. Flower of Aloshya didn't end on a happy note, but Mirror of Targos covers more of their married life and is said to have a happier ending. I really want to read it.

By the time it ends, Kay and Zygril aren't exactly on the same page. Kay is not yet honest about his feelings, and Zygrik is well... A red flag. So many people interpret the ending to be an unhappy one, because it's gonna look like Kay ended up as a prisoner to a tyrant.
But on the sequel, Kay is going to be forced to face his own feelings, and all is supposed to end more happily.

There is a story where the characters really look like these two, can someone help me?

This one? (๑•ㅂ•)و✧

One of these maybe?

K I started it but I don't get it and I need to know before I proceed. Is the husband really shitty? Cuz I am getting mixed messages here. He says Pinky is linked to his powers and seems to love the FL? And if he loved her, why did he leave her alone for 3 years? Wtf is actually the truth?

Just finished chapter 28 and I need a break from the story. Only mild spoilers to answer your questions.
Based on a few scenes and various hints, it seems like the mistress really does have something to do with powers but it isn't the ex-husband. Instead, she's related to his ward. Different plot point, don't want to get into it, and honestly they treat both the mistress and the ward as side characters (only necessary when plot.)
As for the husband? Nah. He's obsessive but he's not even giving "yandere" vibes, which I could maybe overlook. Instead, he's giving major "narcissist" vibes. Him chasing after MC seems to be more about an ego hit rather than out of "love". In one scene, she straight up worries about him being violent with her if she turns him down. He's also not interested in the ogMC, only the current MC, which she finds offensive and same. He basically seems to only like her because she's "defying" him. But thankfully, he doesn't seem to be the ML, so I can forgive him being included in the story.
These idiots don't have a single brain cell between the two of them. They are so stupid omfg.
