Hello, I'm glad you enjoyed it! 💗
It is stated earlier in the prologue that MC doesn't understand what death truly means and you can see throughout the chapter (e.g when MC encounters the dying soldier) that MC is still uncertain on what death looks like. They know the word death but not what it truly means except the fact once people die you can't interact with them. It's almost like an illness in their head, something that can be treated before it's too late.
I hope that made sense, if not let me know! Maybe I should add something like the above in the prologue so it doesn't seem strange. 😅
