I Transmigrated As A Princess Into The Novel I Read

I get transmigrated after I die. Wait. In the princess's novel that I have read?

A common person, Riana Qisha, died after being betrayed by the person she loved the most. Which is her own family and her lover. Her life is full of unfairness. So, she got a chance to meet the condition of Isekai—transported to another world in the novel.

However, she suddenly wakes up in an unknown world as an unfortunate ice princess named Princess Irene Sophia de Grande Santasos. But...

Why was the universe she was in based on the novel {The Tragedy of Winter Coldheart}, which she had read online on a web novel?!

P/s: This is the novel that I created. English is my second language, and I'm sorry if there were any errors in this novel. Thank you for reading! ^^
