Meet four high school friends: Haruka, Takayuki, Mitsuki, and Shinji. Life's promise shines brightly on them until an accident leaves Haruka in a coma. Her boyfriend, Takayuki, can't forgive himself, and seems determined to follow Haruka into a comatose state. Mitsuki dedicates her life to taking care of the tragic young man, and the pair fall into a relationship floundering in guilt. When Haruka awakens after three years, everyone must pretend no time has passed. Torn between his unhappy real-life relationship with Mitsuki and the daydream high school romance with Haruka, Takayuki feels the tiny silver lining left in his life being mercilessly and methodically stripped away.
