Unfortunately judging by the recently uploaded cover, the demon king is set up to be the "I've made many mistakes but I love you so please forgive me" type of love interest and he seems to be the end goal.
It's fun that even in female lead stories the main love interest is still written as an unlikable prick that the author only ever makes effort to make them look worse as a partner than every other option available.
