On the last night of the sixth and twelfth month, Ai has a long history of having prophetic dreams, except for one thing that he never dreamed of...a love story.

But that night at the end of that year, he saw a warm love life in his dream. Ai was with a man who was extremely gentle to him. He couldn’t believe it, that man was P’Yu.

Yu, the brother next door who is best at irritating Ai first, is completely opposite to the person in the dream. Although he has such a bad face in front of Ai, he gradually walks into Ai's heart unknowingly.
