I kinda suspected that was the angle, given the Dragon Mark activation between the end of last and this chapter. Dunno if I fully agree with it because I do sorta feel like it's just a "surprise! You don't actually suffer any consequences!" rugpull of sorts, but it means a happy ending for the two mains, and it's not like this was billed as a tragedy from the get-go or anything.
As I understand it, they still are going to lose their humanity as Euphie will become a Spirit and Anis a Dragon, but they will still be together even then.
