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

I am the villainess in a harem novel. My role as "Erika" is to be an evil ex-girlfriend. I don't want to be a dumb villainess, so I broke up with the male-lead first… But after 3 years, Leo came back to me.

"I can't live without you. I still like you…"

I'm not the girl you should be obsessed with?! The second leads also came to me.

"I like it when you're next to me…"

I'm just a supporting villainess, yet why are all these men confessing to me?! Who should I choose?
