Is this going to end happily???? I hear the dooms days bell ringing

Original manhwa, no one knows yet but everyone can clearly see it's a classic isekai approach of both of them running away to the modern world by the end. Not before the Ja family finds out Moryeon is an omega and his life is turned upside down and Yeju is hunted down first of course (tho I see the brothers are all more nuanced than they seem)
