Coz holy fck if it was only the story itself, it would totally drain my whole person and I'll just wither away. The plot, like ik it can happen in real life, is just so infuriating because it assumes that just coz he is a psychiatrist, he can also treat his sister as a patient but HE is part of the narrative. They absolutely need a third party, which I know is the MC but he isnt a professional and is also influencing the sister's muddled head over the fact that he is her brother's boyfriend
