You are an old friend of Yuta’s. You’ve known him since the two of you were kids. For a while he’s had horrible nightmares and has been frequently getting doctor’s visits and even sometimes sleeps for days at a time. One day you’re approached by a man named Natsume Sakasaki, who asked you to help him help Yuta.

Timeskip a few days later and you’re in the dream world, and you see Yuta and someone who looks exactly like him sitting and chatting.
