Blood-stained battlefield, soul lost in another world - the heroine dies in ancient times, travels to the modern girl of the same name, wakes up in the hospital, meets her best friend, is out of place, and laughs and laughs - the best friend takes the heroine home, the heroine adapts to the chaos of modern life (dressing, using the toilet, looking at electrical appliances), resulting in a funny plot.
Unexpected confrontation, cold encounter - the female protagonist went out and got lost, broke into the male protagonist's company/met the male protagonist, misunderstood due to ancient behavior, and the male protagonist became curious about her.
The road to survival, the first glimpse of the world - the heroine decides to adapt to modern times, her best friend helps her find a job (maybe near the hero's company, or somewhere where she has intersection with the hero), and the heroine starts to learn modern knowledge.
