I Got Transmigrated!!!.... But in a War Book??

Lee Han Eul, a normal college student, got transmigrated. It was something she always dreamed of, for that she had always read novels with reverse harem endings, full of handsome men and princess life. But, when she opened her eyes, it wasn't a beautiful rom-com, where you could conquer male leads, but it was a R-18 violent, war theme book, with zero romance. It was supposed to be okay. But, the character which she had transmigrated to wasn't exactly a great choice.
