Well, the copywriter is incompetent. It's probably a story about Xia Shouyu, an ordinary college student, who encounters ghosts in life, and then develops friendship and becomes ambiguous with someone by the way. Alas, I really don't know what other label to use besides the label horror story, but horror really doesn't count... Tangled.
As for the specific plot and so on, hahahaha, just follow the circumstances, just click on it and it will be fate.
