Does anyone know the title of this manhwa?

There is one manhwa where the female lead got scammed by reading apps, and then she ended up going inside the novel she read. Inside that world she transmigrated in, there are a lot of girls other than fl transmigrated (got scammed) too, the timeline they got transmigrated is different for each one of them, the fl apparently the last girl that got transmigrated, and each one of the girl has their own story and male lead. Also, the female lead and the transmigrated girls have a system or device for communicating with one another, kind of like a blog, the girls able to post something, make a comment, etc. The last time i read, the fl is exploring an area that is not yet on the map with some important male protagonist (i think the prince and the duke?? I forgot really), priest girl and chinese princess girl.. i think.. uh.. i forgot.. and then when they reaching the unknown area, immediately, the fl separated from her party.. that's all the last chapter i read of that manhwa..

Anyway.. does anyone knows of this manhwa, it is kinda interesting, and i lost it. No matter how many times i search i did not found it ╥﹏╥
