This is strange way to end a series imo. Rather than this dream it would be nice gyuyong's dream is precognition dream: Like we get to see a glimpse of adult gyuyong and gyuchan, and perhaps middle age gyuha and chayong when gyuyong finally brings his significant other to his parents. Something that not set in stone but enough for readers to see happy lives of their family.
