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.
