Aren’t I the Female Lead?

I transmigrated into a novel. Not as a villain or an extra, but as the female lead.

What luck is this! An older brother with a sister complex, and two handsome men as childhood friends.

Where else can you find such ‘female lead buff’?

…But wait a minute,

The original male lead, the Little Duke, likes another woman?

And she’s like me, who transmigrated in the novel?!

“This is a secret. It’s been a while since I’ve actually liked Little Duke.”

“If I say I’m dating Lady Dana, is there a problem with you, Ariel?”

Wait, aren’t I the female lead?

I can’t do this. I’ll just throw away the original male lead and live happily with the pure sub male lead.

The male and female lead roles, take them all!
