Idk if I'm just dumb but I got confused reading the description. So wait, the girl gets reincarnated as the male lead's stepsis right? Or are they not step siblings? Are they related? She has a brother, so is her brother also the brother of the guy? Is the guy from the picture her step bro? Do they have THAT kind of relationship? Please someone explain because I'm hella dumb!!!!

From what i have understood she was the author of the novel she reincarnated in and her role there is the step sis of the main lead who were killed in the novel, now to prevent that she want to do things rights like fixing their debt and etc. by acting as the temp head, cause mc is still not in age, for their relationship from the current chaps they doesn't seem to have the romance shez or something just kinda purely step sis who i might kill and step bro who is the mc i wrote might kill me, thou at some times the female lead do gawk or something at the mc but i don't think its in the romance category more like fan category.
And lastly u should try reading it, its quite good and the fl is sassy and got the right attitude, welp that's how i see it, u should try it, goodluck

Anyways, since they're siblings ON PAPER, one might question the ML's morals for falling for the FL, but for me, I'm fine with it. I mean, the mother and father are both dead and they don't have a half sibling tying them together so they're both basically strangers living under one roof at this point.

She has a little brother that was conceived between her mother and the ML's father. After her mother gave birth to that son, she started treating the ML badly.
The main character has no blood relation with the ML. IN the first place, incest is bad because the child they conceive will have many problems such as having a weak immunity and etc.
There are also some stories I read where a family adopts a daughter to raise her into their daughter in-law but the children's marriage is not set on stone.
Was that a Here U Are book on the last page before the credits???
