在一个宁静而古老的村庄里，有一间被岁月抚养成温暖与智慧共存的小店。这里 sells nothing but a bottle of perfume, called "Lancome Miracle". The store is owned by an old man named Mr. Lao, who claims that this perfume has the power to transport people back in time.
The story begins with a young woman named Lily who lost her beloved husband in a tragic accident. She is heartbroken and cannot find peace no matter how hard she tries. One day, while wandering around the village, she stumbles upon Mr. Lao's shop and hears about the magical perfume.
Intrigued by the idea of meeting her loved one again, Lily decides to try it out. She buys a bottle of Lancome Miracle and applies it on her wrist as instructed by Mr. Lao.
As soon as she smells the fragrance of Lancome Miracle, Lily feels herself being transported back in time to when she was still with her husband. They spend their days together again just like they used to before his passing away.
However, every time Lily wants to return to reality or tell others about what happened after using Lancome Miracle，she finds herself stuck in this past world for longer periods than expected without any explanation why it happens or how long it will last each time.
She starts feeling confused and worried because if something goes wrong during these trips through time，there may be consequences that could affect not only hers but also other people's lives.
Mr.Lao reveals that he himself had been living through different eras for years ever since he discovered this mysterious potion，but at great personal cost: each journey takes away from his life expectancy.
He warns Lily that there are risks involved in using Lancome Miracle，and once you start down this path，it can become very difficult to stop。
Despite knowing all these risks，Lily finds herself unable resist visiting her beloved husband whenever possible due to deep emotional attachment between them。
She confides everything into a close friend who suggests seeking help from experts such as historians or scientists possibly able solve some mysteries surrounding Lancombe miracle's true nature while minimizing its potential dangers
Together they work tirelessly until they finally discover an ancient text hidden within library archives which speaks about an ancient civilization known as 'Chrono'.
This Chrono tribe possessed knowledge far beyond modern times；they were capable creating potions allowing them travel across different eras based on user intentions（intentional journeys）or emotions（emotional journeys）
They used these potions mainly for educational purposes rather than entertainment、and understood well enough their own limitations & risk factors associated with such abilities
Upon learning more details regarding Chrono Tribe’s potion-making techniques & safety measures taken during usage,
the group devised ways modify Lancombe miracle formula so users wouldn’t get trapped too long nor suffer negative side effects; thus making use safer yet still maintaining essence magic behind perfume
With newfound understanding and hope restored within hearts of those affected by tragedy,
they continue enjoying shared moments cherished memories thanks largely owed support offered both friends strangers alike;
in doing so ensuring history remains alive even though sometimes painful lessons learned along way remain part our collective consciousness forevermore
