The man who raised me as his own daughter was murdered. Deciding to use my save&reload ability, I turned back time to a previous safe point. The problem is, out of my four time slots, he’s only alive in the one where I’m seven. Welp, it is what it is. Repeating some life is no biggie, so let’s start over. Elysion, giving off a weird vibe, pulled me aside. He’d been a close friend even pre-reset. Is this happening? [Overwriting Time Slot 1 with current point.] “I love you, Tania. I’ve liked you for a long time.” “Ah, I’m finally getting a confession…!” Overcome with excitement, I immediately loaded the save point so I could hear his confession again. [Time Slot 1 Loaded.] [Time Slot 1 Loaded.] [Time Slot 1 Load…] [Time Slot 1 …….] I’m not sure how many times I replayed his confession. Elysion’s face turned so red that it looked about ready to burst; he parted his lips with a troubled look. “Tania. If you want, I can tell you as many times as you’d like, but could you at least give me an answer to my confession first?” “What…?” Shockingly, he remembered everything I did. Instantly, everything I’d done in front of him flashed through my mind. Like, I would often look at his face, muttering to myself about how handsome he was. And how every time I wanted to see him, I would go up to him and touch him, making him distressed. And most importantly, how I had just turned back the clock by twelve freaking years just because I wanted to. I really didn’t think he would end up remembering all of that. **Original Webtoon:** [KakaoPage](https://page.kakao.com/content/69138565), [Daum](https://webtoon.kakao.com/content/%EC%84%B8%EC%9D%B4%EB%B8%8C%EB%A5%BC-%EC%83%9D%ED%99%9C%ED%99%94%ED%95%A9%EC%8B%9C%EB%8B%A4/4853)

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!
