I Am the Male Lead's Ex-Girlfriend (Pre-Serialization)

The original Erica was written as the pitiful ex of the novel’s male lead, Reo. Now that I’m her, I refuse that pathetic side role, and I’ll cast him aside first! But then again… the way he looks at me, with those gentle eyes… No! I must stay strong. All the male leads fall for Juliana anyway. I can’t compete with her (she’s the protagonist!), but it feels like these men are throwing me into the ring! Should I let the plot run its course or save a few broken hearts and give my destiny a rewrite? (Source: Tapas) *Note: Chapter count includes 15 side story chapters.*
