A man decides to use a new technology to go inside the mind of his comatose lover.
Koichi and Atsumi are childhood friends who eventually fall for each other and become lovers. Atsumo, however, commits suicide, but instead of dying becomes comatose. Thanks to a new procedure Koichi is able to enter Atsumi's subconscious mind in order to understand what prompted the suicide. Upon entry into his lover's subconscious mind he asks her to locate a drawing from her childhood, which is the key to the minds' melding and unravelling the mystery of her actions.—aghaemi
Koichi (Sato) and Atsumi (Ayase) are childhood friends who have become lovers. Despite this closeness when Atsumi attempts suicide Koichi is at a loss to understand the circumstances that drove her to do such a thing. Now she is in a coma and Koichi needs to find out the reason. Since Koichi is a neurosurgeon he has access to the latest studies and so he takes part in a medical procedure that will allow him to enter Atsumi's subconscious. Through 'sensing', a type of neurosurgical procedure allowing contact with the intentional aspect of a comatose patient's mind, Koichi tries to discover why Atsumi tried to kill herself, and to bring her back to consciousness.
When he enters her mind she asks him to find a picture which she drew as a child. It is the key to a suppressed memory connected to a childhood trauma, an incident buried in their past which will bring their minds together and allow him to get close to truly knowing his love.
