Sleeping Bride (ガラスの脳, Garasu no Nō, "Glass Brain") is a Japanese 2000 romance film directed by Hideo Nakata, based on a comic by Osamu Tezuka.
However, for a reason inexplicable by the science of the day, the daughter (named Yumi) does not wake up and is essentially in a comatose state.
Her wealthy father has her placed in a hospital where she will be cared for indefinitely (and also offers a reward to anyone who can wake her) while he vanishes in search of a cure to her condition.
Seven years later (March 25, 1961) Yuichi (a boy who is roughly seven himself) is admitted to the same hospital (with asthma) and discovers Yumi.
After being told of her condition and then reading the story of Sleeping Beauty, he resolves to awaken Yumi by kissing her.
This has no effect, but Yuichi is undeterred, and makes a routine of this, even after he leaves the hospital, repeating the same line and kissing her.
Overcome by the memories of his childhood, Yuichi returns to the hospital, and although initially thwarted by a new (apparently American) nurse, he eventually resumes his ten-year-old routine, with similarly little results, although more genuine emotion.
Promptly, the silent Yumi is besieged by a team of doctors and nurses who start to run series of tests, essentially ignoring and shutting out Yuichi.
Upon sighting a bus (which Yumi seems to want to ride) Yuichi decides to give the orderlies (who have the air of cartoon comic-relief thugs to them) the slip, and does so successfully.
She declares that she only has two more days left before she falls asleep again (she gives no explanation as to how she acquired this knowledge, but she simply has it).
On the fourth day, Yuichi's old nurse returns to the hospital to see Yumi, who is now in a state of depression.
After hearing the story from Yuichi, she reveals that Hikawa had been doing something sexual to her at night, and that she left the hospital upon discovering this.
Hikawa does not get up, but simply talks, his head lying down, not facing anything, of how Yumi was abandoned by her parents, and God.
Yumi explains that she heard someone, for a long time, praying for her to wake up, and then felt something that made her feel very warm.
Twenty seven years later (August 7, 1999), an aged Yuichi, now a scientist, returns home from work and talks to his wife.
