Lucid dreams.

Dreams where you know that you're dreaming.

After an accident in his youth, Tooru Naitou began to have nothing but lucid dreams. Always being aware of when he's dreaming meant that his mind could no longer rest when he was asleep. Only when he collapsed from utter exhaustion does he finally get a reprieve.

Lucky for him, he has a childhood friend, Saki, who insists on calling him 'Nii-san' that tries to do what she can to support him. In his science club, his senpai Yayoi is endlessly amused by his awkward way of living. And he has an underclassman, Keiko, who likes to sing in front of the station and likes to call him weird for his less than normal attitude towards life.
