He made a choice, and it all started because of a terrible mistake. Can Norman and Nina's childhood sweethearts be the guarantee of their marriage? Is it a coincidence or a deliberate arrangement for Leda and Kent to return to China at the same time? Can Rose tell her inner thoughts to her husband? Can Ruf and Neil and Jacob still be together if they are in love? Are memories of Norman's childhood the key to unlocking secrets? Can the misunderstanding from twenty years ago resolve the grievances between the three families? The curtain of everything is opened in "Memories in Sleep".
