How to Get on the Main Character’s Flower Path

Chapter 40

578

Life never goes according to plan—something I had yet to learn back then. Because of a friend from my past life, I begrudgingly read a male-oriented fantasy harem novel… only to wake up as a character inside it: Kang Nahyun. Special perks for reincarnators? Ha! As if. I had no money, no connections, and nothing but a hardcore survival mode to keep me going. But just before high school, I awakened into the “Sniper” position, earning myself a spot at the Awakener Academy! And if I can’t be the protagonist, then I’ll just hitch a ride on the protagonist’s flowery path, right? So I make it my plan to stick close to Na Yuhan, the real hero of the story, snag a few scraps of luck, and quietly bow out… Except something feels off. With every passing day, my steps are veering further and further from the plan… The chaotic Academy life of sunshine-heroine(?) Kang Nahyun begins now! “How to Walk the Protagonist's Path of Flowers” — coming your way!
