Su Xiaotang has lived for 22 years, and what she is most proud of is that she has lived a "bad" life into a "Buddhist check-in" - working as a "fish shopkeeper" in a cultural and creative store during the day, and staying in a rental house at night to catch up on fantasy dramas. The only "non-Buddhist" thing is that every Chinese Valentine's Day, she goes to the outskirts of the city to place a wishing lantern under an old locust tree to commemorate the bamboo horse Lu Xingci who has disappeared for five years. Five years ago, Lu Xingci suddenly disappeared on the night they agreed to watch a meteor shower, leaving only a silver pendant with strange patterns engraved on it. Su Xiaotang spent a whole year in emo before slowly accepting the fact that "he may never come back."
Until one day, a strange customer wearing "ancient costume" came to the cultural and creative store. He stared at the silver pendant around her neck and suddenly asked, "Where did you get this 'Star Pendant'?" The moment Su Xiaotang looked up, she was immediately confused - this face was clearly Lu Xingci! But the other person's eyes were strange, and he called himself "Ling Guang", saying that he came from the "Star Weaving Realm" and was the "Guardian Saint" who guarded the passage between the two realms. What's even more outrageous is that he said that Su Xiaotang's silver pendant is the key to opening the passage between the two worlds. The passage has been unstable recently and only she can help repair it.
