Let's Make Saving a Habit

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)
