Hwayeong is a Korean female who lost her boyfriend to her best friend (Just me or the boyfriend and the prince look alike and the best friend and Irene look alike?), and that same day, she accidentally fell into the Han river. And to pile up more of her bad luck, when she wakes up she finds herself to be the daughter of a famous duke, Chartiana Altizer Cailon, who is an evil woman?! Chartiana was also appointed as Regina (next empress candidate).

Just at the age of 15, Calliope began to suffer from various accidents, leaving everything she had ever loved to perish and war arose. But a beautiful white-haired woman took her back in time when she was born. Will our heroine be able to figure out how the accidents began and stop them before it is too late?
Calliope is adorable, and the art is really nice. I'd say if Isekai novels are your go-to, you should read this one.
