How to Get on the Main Character’s Flower Path

I was reincarnated in a male-oriented modern fantasy novel that I read as a boredom reliever. I expected a paradise life with the reincarnation privilege, What I was given was the role of a hardcore life as an orphanage’s oldest sister with younger siblings to feed! In the face of a financial crisis, I finally made up my mind. To get on the ‘main character bus’! In other words, becoming a member of the male lead’s harem. Heroine? I’ll do anything. If I can make money by doing it! My goal is to become a common sub-heroine 1 and eat rice cakes, If I earn as much as I can, I will naturally leave later. However… [Character ‘Kang Nahyun’ appears in “Academy’s F-Class Commander”.] [Readers’ responses have been updated!] – What is it? The heroine? – As for an academy, harem is my favorite. – DBH! DBH! (DBH: die before becoming the heroine) What else is this? *** …Obviously, my first goal was to be a minor sub-heroine. – F*ck at this point isn’t the female lead definitely Kang Nahyun? ㄴAgree – The fact that Kang Nahyun is the female lead is regular in the Academy I didn’t know then, that life doesn’t always go as planned.
