In the novel its actually more sadder when she beat up in her past life its because her brother friend told that she is been called by her brother but actually they just scam her and beat her up thats why she say that she beat up bcs her second brother
When her brothers treated her like an outsider, all of the people will take an advantage to bullies her. For me, I agreed with the FL that all the bullied happens because of her own brothers. Coz the root of the problem started from his brothers not her.
At this moment we know that somebody ass will fucked up
