Yes, there are some K - dramas titled 'Glory' that are based on true stories. These dramas often draw from real - life events to create engaging and thought - provoking storylines.
I'm not aware of any particular 'glory kdrama' based on a true story to recommend. However, in general, many K - dramas are inspired by real - life elements. You can try searching on drama - specific websites or forums where fans might be able to point out such dramas if they exist.
Another theme is exploring the backstories of the characters more deeply. In the actual drama, there may not have been enough time to fully develop all the characters' pasts. Fanfictions can fill in those gaps, like delving into the character's family history or how they came to be the person they are in the drama.
