I don't have the link for the novel since I only read the spoilers, but I can send you the link from Novel Updates. The one who posted it shared the summaries for both part 1 and 2. Here's the link:

I don't know if they are gonna follow the novel but I think this is just the finale for part/season 1? From what I have remembered in the spoilers, there's part 1 and part 2 and there's like side stories every ending for each parts. For this season, the side stories are about the couples' daily lives, Ray doing his self-experiment and advancing his wizardly rank, a duel between the two couples and etc.
In part/season 2, we will see the peace talk between El Fasher and Strass, Ray meeting Edrich (brother), the revelation of his death, and MC knowing that his own brother has a thing for him
