After dying from overwork twice, a woman is reincarnated into a fantasy world for the third time as a village girl named Melia. Having first died as a Japanese office worker and then again as an alchemist in her second life, she is determined that this time she will enjoy a slow, peaceful existence. Unfortunately, her new life as a twelve-year-old orphan in a poor rural village proves difficult to sustain on her own. To secure the bare minimum living conditions, she secretly begins using her inherited alchemical abilities to create and sell potions.

However, Melia is unaware that alchemy has become an obsolete and forgotten art in this era. When her use of alchemy is discovered, she is suddenly taken away from her village, derailing her plans for a quiet life. The story follows Melia as she navigates the consequences of her actions, encountering new circumstances and characters that pull her further from the slow life she desperately wants. Despite repeated twists of fate, she continues striving to carve out a comfortable and unhurried existence for herself. The narrative progresses through her struggles with poverty, the unexpected attention her rare skills attract, and her gradual adjustment to a world where her abilities are both a blessing and a complication.
