Everyone has their own secret. Xu Xi always sticks to his own spiritual territory, where there is only his own doll "cousin" Xu Nan. Si Qing seemed to be an accident, a foreigner who set up camp after breaking into Xu Xi's territory. But once this foreigner steps in, don't think about leaving easily. Xu Xi will drag Si Qing into the trap. Si Qing also has a secret. He inherited the special ability from his mother who is a magic stick. He can always see some dark creatures wandering in the world and unwilling to leave.
Concept: Alone out-of-the-way. This in itself is a condition characterized by endlessly performing the same actions with no clear cause. Even when you stop these unconscious movements, the patient becomes manic and furious, and they are very territorial. They will repeat the actions they were taught when they feel like it, but expecting them to shout long live and have fun seems like a luxury. Xu Xi is like a patient suffering from autism. He learns to repeat the teachings of his teachers and elders, and be what a child should be like. Because he only repeats stiffly, he will be different from the living children, so he will be isolated and hurt by people whose instincts drive him away. However, there are two "friends" that belong to him in his territory, "cousin" Xu Nan and "shadow" Shou. For Xu Xi, "cousin" is a vanguard who can lead him to avoid the crowd. It is his so-called bright side according to the world. The bright side is beautiful, she is the hope born for Xu Xi. But this Liang also had an almost paranoid protective desire towards Xu Xi. Opposite of the bright side is the dark side, and the "shadow" monster with full hands is perfect for it. "Shadow" is violent. What he believes in is that anyone who hurts Xu Xi will be attacked directly by him. His hard shell is filled with tenderness towards Xu Xi, which is softer than the shadow. In fact, compared to Xu Nan, she is a more solid existence. She can abandon herself and make herself disappear because Xu Xi does not need her. In order to avoid the harm caused by the "shadow", she can calmly find Si Qing, the best protector for Xu Xi, when she decides to disappear with the "shadow". As if by accident, Si Qing interrupted Shadow's first display of power, which made "Shadow" look like a malnourished defective product. Si Qing slowly replaced Xu Nan, and Xu Nan no longer needed to guide Xu Xi to escape. Si Qing can be regarded as a foreigner who set up camp after setting foot in Xu Xi's territory.
