This is the waiting more persistent than Silent Separation; He Yicheng spends seven years waiting for his true love while Le Mingshen spends his whole life waiting for familiarity. Someone says the most beautiful oath is to remember the loved one deeply in one’s heart to make the love never change until death. However, when the brain loses the memory, the most beautiful oath becomes eternal waiting..The most painful thing in the world is waiting; the longest waiting in the world is the people that forgets you in the next second. In her world, you have never been in her world. Can you persist on the waiting? This is the warmest journey of memory loss. In this world, many people will walk with you for a whole; however, there is only one people who is willing to hold your hand again and again back home. Introduction to the story: at the age of 18, he fell in love with her; at the age of twenty seven, she fell in love with him; however, in this year, she forgot him...Le Mingshen thought for many times was this because he confessed too late? Therefore the God punished him. When Tao Xincheng suffered from “Repeated Amnesia”, he started to confess his love to her repeatedly. Faced with the beloved one who forgot him repeatedly, the life of Le Mingshen was left with repeated self introduction, acceptance of suspicion, acceptance of rejection and acceptance of himself...until one day, she suddenly forgot him again. Regarding “Repeated Amnesia”, the forgotten one suffered the most. However, there were only two people forgotten: Tao Jingluan, father of Tao Xincheng, and Le Mingshen, the psychologist. Le Mingshen determined to rescue Tao Xincheng.  )
