"he has an excessive anxiety disorder that made him unable to get close to anyone, even his own parents, after the death of his eldest brother when he was eighteen years old. Now that he is twenty-eight, ten years have passed." Max recited what had been ingrained in his heart, while pushing the handle of the ivory-colored bedroom door that had never opened since his arrival to this mansion, two Sundays ago.

Max graduated in psychology, one of the top ten graduates of his university in England, Oxford University. After working for a few months, he was immediately transferred to become the personal psychiatrist for the youngest son of the Nakamoto family, one of the richest families in the world.

After the death of his older brother, it was supposed to be the youngest Nakamoto who took over the famous electronics company, but here he was, locked in a cage due to excessive anxiety after the death of the elder Nakamoto.
