I hope you won't be disappointed about the ending!

Didn't u read the further spoiler? I heard Reeze was Divorced and band from the empire coz she was flirting with the Prince and other reason too. Now she stuck in this world like any ordinary person coz Edith snatched her powers after completing all the 3 stages

No. Cliff and Reeze marriage won't last long. Cliff married another woman at the end as his 2nd marriage.

wait where did you read the rest???

There should be more story after their marriage. She became worse and the obsessive Cliff no longer able to tolerate with her behavior.

From raws side stories and novel spoilers. She was sent to monastery at the end.
I copy and paste "She decided to present a fake lost relative of the imperial family and when she was found out, she was sent to the dungeons. She was sure she would be beheaded, but coincidently, Edith found the real one and as a prize, asked the emperor to release lize and to not hold a grudge against the Ludwig family. The emperor agreed but with the condition that Lize is sent to a monastery and lose her status as Cliff's wife.(She made a clause in the marriage contract that he could never ask the divorce,but the emperor can do it)".

Cliff remarry another woman with brown hair, I believe she is not a nobel, not a rich, not a beauty either.

your spoiler is incomplete bruh that was not the end
