The moment she was kissed by her brother before he told her that he is her brother then kidnapped her in the open without even explaining everything thoroughly is a red flag for this manga. Plus FL just let them do what they want because the "love" her is also fucked up. I also began wondering if these brothers molested her when she was a child because of how they suddenly assaulted her when they saw her. Anyways, don't bother reading. It'll just make you say wtf all the time.
