I have read every novel by Keigo Higashino, but the one that impressed me the most was Nocturnal Walking, a guardian who put all his eggs in one basket for 19 years, because the cool thoughts of love turned himself into a murderous genius at the first sight of the snow ear. In those darkest years, they were each other's only sun. What saddens me most about watching the complete drama is not the death of Liangsi. Maybe he thought about bringing the worst consequences to himself from the moment he decided to protect Xuesui, but Xuesui's indifferent words made me feel particularly depressed: I don't know, and she didn't look back. She knew everything, but chose to turn a blind eye, not only to Liangsi, but also to her past.
What they have is love, but the deformity of family and the indifference of society lead to the psychological distortion of Liangsi and create their sad love. Too true portrayal and too depressing story, the most painful love is that I take care of you, and you have to go the rest of the way by yourself.
