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??Agree The fact that Kang Nahyun is the female lead is regular in the AcademyI didn't know then, that life doesn't always go as planned.
