In the era when the Berlin Wall was high, the war was not far away, and people's hearts were already broken.
Li Dan is a calm and restrained doctor of psychology, while Klaus is the person being observed in the isolation experiment.
She thought it was just a standard experiment, but she didn't expect that from the first day she walked into the observation room, he would never come out again.
In this man-made "isolated island", she is the only person who can enter his world.
Klaus learned attachment, adoration and love here - the way he looked at her was like a pilgrim looking towards the light.
But Li Dan knew that this "love" was just a psychological illusion under experimental conditions.
"I love you."
Looking at the burning emotion in Klaus's eyes, Li Dan felt only confused.
In this completely isolated cage experiment - do you really love me, or can you only love me?
