I actually don't remember but what I do remember was the FL was in prison and the door was locked with a spell but when she looked at it she could see like an easy code we use in our world but to them its like a high level magic spell which she easily unsolved and unlocked. That's all I remember from it and I've been looking for this manhwa for a year now lol so I'll check it out and see if it's the one thank you so much!!!

I know I've asked before but I'm looking for an isekai manhwa where the magic in this world is computer coding! If you know the manhwa please lmk thanxx!!
