bruh I need help. I’ve been trying to find this seulrene book and damn it’s frustratingly annoying that I forgot to save it. It’s about how seulgi sees this picture of Irene, and also finds her belongings. Irene lived a long time ago, and she was already dead. Seulgi met this science professor and went back in time to save her from dying . Successfully did that, but ended up being Irene to her own generation.
If you know the name of this book please tell me
