What happened to Champa is really sad, and I feel for girls like her, but she brought what happened to her upon herself. She left her house with a boy willingly, and got herself pregnant. Who's fault is that? She wasn't in such a bad situation that she had to run away. Her mother was only strict with her in the beginning because she kept meeting that boy. Champa was old enough to know she was doing the wrong thing.
I don't feel as sorry for her as I did with Gehna, or other characters who had bad things happen to them.
