Akira is a popular novelist with amnesia. The man who has been caring for him since he woke up in the hospital, Yukiya, is not actually his younger brother at all...?!
On top of that, ever since the accident, Akira has been having vivid dreams of him and Yukiya doing far more than just kissing. What does it all mean? Why is Yukiya really by his side?
As Akira's suspicions grow, he begins investigating their relationship. Eventually, Yukiya reveals the truth to him:
"The first one to lie was you, Akira."
