I've been looking and all i get is the girl is always from the present time . 

I wanted to watch an interesting story of a girl from the past being amaze about how girls can live so much better in the present and living her best life cause the past for her was sucky :/

maybe like" live up to your name " final after credit scene 

Maybe Legend of Yun Qian? The FL is from modern times but she switches places with a female character from ancient times.

Or maybe Hotel del Luna? Not time travel, but the FL was born in ancient times but is cursed with immortality and survives into modern times (and indulges in the material benefits of modern life). 

Mr queen,  the, king eternal monarch . Although you can click on the link :
