She might get angry right back. Ginny is a strong - willed character. So, if Harry yells at her unjustly, she could stand her ground and yell back, not willing to be pushed around.
Sometimes, she could be hurt and run away. If Harry's words were particularly harsh, Ginny might be so hurt that she doesn't want to face him immediately and decides to leave the scene to collect her thoughts.
Ginny might get angry and start to avoid Harry. For example, she could stop sitting with him at the Gryffindor table during meals. She'll be short - tempered when he tries to talk to her and give him cold stares.
One possible reason could be miscommunication. Maybe Ginny did something without fully explaining her intentions to Harry, and in the heat of the moment, he yells. For example, if she made a decision about their relationship without consulting him first.
She might be shocked at first. Since Harry is yelling, which is out of character for him in many cases, Lily could be taken aback and not know how to respond immediately.
Peter might be initially shocked and a bit scared. After all, Tony is like a mentor to him. But then he could become defensive, trying to explain his actions or point of view.
He could also feel a great sense of anger. After the shock wears off, he might lash out at Ginny, demanding an explanation for her actions. His anger could be so intense that it might cloud his judgment for a while.
She could also become cold and distant. Instead of engaging in a shouting match, she might simply walk away and give Percy the silent treatment. This can be a powerful reaction as it makes Percy realize that his yelling has pushed her away and he has to make an effort to fix things.
Ginny might initially be heartbroken. She could retreat into herself, feeling betrayed and confused. In some fanfictions, she may cut off all contact with Harry immediately.
Ginny could be heartbroken. She might initially be in denial, thinking that Harry will change his mind. She has loved Harry for a long time and expected a future together, so this refusal would be a huge blow to her emotions.
Ginny could be heartbroken. She might have expected to marry Harry after all they've been through together. She could initially go into a state of shock and disbelief, not understanding why Harry has refused.
She could also be very hurt and go into a state of deep sadness. She might isolate herself from Harry and their mutual friends for a while. Ginny would likely question her own self - worth and wonder what she did wrong in the relationship. But as time passes, she might find the strength to move on and focus on her own life, like her career or other relationships.
