I finished episode 7! I can't continue this!! Where is the story development?? And why is a freaking thirty-year-old woman acting like she's ten with little to no IQ?? I’m tired. Most of the episodes so far are just filler moments. Why do Chinese writers always drag out most of the shows?? When I started this, I thought, "This seems good! I'm glad I found something similar." In the past, I watched a K-drama called Blue Birthday (if I remember correctly). It’s similar to this one—it also has time travel. I mean, it’s similar, but with the difference that the female lead goes back to save her crush, while in this one, she doesn't even know him. Anyway, in short, it reminds me of that show. Go check it out; it's really good! But as for this one, I’m dropping it, and I probably won't pick it up again. The female lead is annoying in so many ways. Such a waste of my time!

edit:After reading some of the comments and getting spoiled (which is fine since I won’t watch it), I realized it has no similarity to Blue Birthday in terms of direction. The idea at the start is almost the same, if I remember correctly, but aside from that and the time travel aspect, the shows have nothing else in common.
