I didn't know it back then, but life never goes as planned. Kang Nahyun, who was reincarnated into a male-oriented fantasy novel (a.k.a. harem story) that she had reluctantly read because of a friend from her past life. Special benefits that one would typically expect as a reincarnator? What benefits? She had to endure a hardcore life without money or connections. But just before entering high school, in the winter, she awakened as a "Sniper" and was given the opportunity to enroll at the "Guardian Academy"! If I can't be the protagonist, why not just sneak onto the protagonist's flower path? With that in mind, she plans to stick close to the protagonist, "Na Yuhan," at the Guardian Academy, snag a few benefits, and then quietly disappear... But something feels off. With each passing day, it seems like she's drifting further away from her original plan...? The tumultuous academy life of the sunshine heroine (?) Kang Nahyun!
