In the minds of everyone who had ever met Xu Can, the name "Xu Can" was neither a noun nor a pronoun, but an adjective.
No one could have predicted that Xu Can, once so outgoing and lively, would suddenly vanish without a trace. When they saw her again years later, she looked forlorn and desolate, with none of her former pride or sunny spirit. She was timid, her eyes dull, and she had forgotten everything, including her own name. The girl Xu Can had once saved felt it was her responsibility to save Xu Can in return, just as Xu Can had appeared in her gloomy life like a ray of sunshine when they were young.
Theme: Life has its ups and downs, and the road is full of bumps.
