Someone give me a summary I forgot the plot and haven’t read it in years

Basically MC opens her eyes and suddenly she's a character on a webnovel and when she's supposed to avoid and do bad things to her bff(real mc) she changed her plans and so on ( she got friends, bf and etc). She comes back to the original world every march 2nd but not this time and she's still figuring out how she can do that dimensions travel something

There's too many events but this is the only ones I can remember

So is she aging in the real world or reliving the same March 2nd?

Only reliving on the 2nd day of march
