I Transmigrated into the White Moonlight of the Water Prince

I was transmigrated into the world of Ye Luoli as the woman the Prince of Water fell in love with at first sight. He dotes on me and kills for me, but only I know that in three months, he’ll plunge an ice spike into my heart with his own hands for the human girl who comes along later. Since there’s no System, I’ll change my fate myself. But when I really do change the future, he asks me, eyes red, “Was I nothing but a pawn to you from beginning to end?”
