Vietnamese girl in abstract painting

The novelist Yoon Hee (Cao An) saw a creative crisis because he could not find fresh material. After learning about the legend of "muoi" from his old friend Seo Young (Cha Ye-ryun) who is now living in Vietnam, Yoon Hee decided to start a new novel based on the legend. However, because the previous novel alluded to Seo Young and contained many falsehoods, Yoon Hee felt anxious before going to Vietnam. Yin Xi was greatly surprised by Xu Ying's changes and enthusiasm, but the unnaturalness when communicating with Xu Ying did not affect her enthusiasm for "muoi". However, when she became more involved in collecting related work, all kinds of incredible strange things began to happen. Yin Xi gradually felt that Xu Ying in front of her was possessed by the "Vietnamese girl in the abstract painting".
