I Saw You In My Dream, is really the story of two neighbors, one house had two sons who were left alone after their parents passed and the next house had one son and both parents there. His parents helped looked after the neighbor boys so they almost grew up as one family. Around the time the one son (with the parents) is 20 he starts to have dreams that predict the future and most of them revolve around the older son that lives next door. In time they do get together. As it turns out the younger brother is also gay and he partners up with the son's best friend. I won't give away the whole thing, but will say it does have a happy ending. There are 12 episodes of the main story and then one more episode that jumps ahead about four years. While the series was enjoyable, I have to say that the main character (with the dreams) is very immature and a bit self-absorbed. For example, he accidentally breaks the other guy's phone and doesn't even apologize. Then there is another guy who likes him, but he doesn't like him back and has no qualms about hurting his feelings. I mean he wasn't obnoxious, but he really needed to grow up. As for the 'older' brother, they don't clearly define how much older he is to the twenty year-old, but I would guess maybe four or five years.
