A lot of people have stopped reading because of this so:
People are either confusing the plot from the book FL read, where the ML was the villain who raped her brother who was the protagonist, with the actual story where she is the protagonist. Or they are either misinterpreting a scene
SPOILERS:
The scene being misinterpreted is the one where the FL is asking Aster to let her go, Aster tries to convince her to stay and kisses her. She pushes him away and tries to escape. Aster then grabs her hand not letting go, not with the intention to harm or her or SA her but tryiing to stop her from running away. The FL tries to resist and in the process stabs Aster in the eye, and she runs away. Aster is cries and still begs her to stay.
He doesn't hurt her or attack her, he has no intention of SA at any point. The kiss he gives her, while unrequited was without the intention of doing it against her will. Please stop spreading misinformation. I nearly stopped reading this manga because of the comments.
