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

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 just know they were meant for each other. Like, there's no one who can handle Seonwoo better than Taeseo. And despite Seonwoo's personality, he always gave in to Taeseo's silliness even though he finds it annoying most of the time. He really needs his sunshine in his dull and dark life. They are such an interesting couple, definitely better than the main CP
I saw the raw chapters of this part before, this is gonna be hilarious. And yes, the other guy is kinda shameless even after being on the same situation. And the instructor(?) will join the fun, too
Pls link to the raws pls pls pls
