Is my existence destined to exist for the existence of others? Like a shadow, if I am needed, I just need to walk under the sun and let the shadow lengthen and shorten; if I am not needed, I will walk to the dark corner, and the shadow will become a hidden child. Without leaving a trace, if, I mean if, if there is an afterlife, can I live just for myself and only for Nangong Ziling?
