Does anyone know the title to this? I'm not sure if it's isekai or time travel but there's a female lead who was a tyrant before. I remember that she lived her life again or isekaid and was more careful of how she went about her life. In her previouse life, there was the son of one of her knights whose father was killed due to her. That boy set out to get revenge. Initially he didn't want to follow his father's foot steps but after his father's death he became the best knight of the land.

In the new timeline the queen/princess(?) prevented the death of the commander and she told his son that if she ever strayed from the path then he should kill her. I don't remember anything else. I remember she teleported to where the knights were cornered and joined the battle. The commander knight was initially supposed to die buried under the rocks I thibknk?I had this bookmarked in mangadex before so I can't remember anything else..
