How Could the Villainous Young Master Be a Saintess?

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious.  When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before.  At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?”  But then… surprise! He’s not just the villain—he’s the “Saintess”!
