This has got me sobbing. I hope they all end up happy as a family. Honestly, if that happened to any one of my family members and they ended up dying or killing themselves I’d do that too. I think if the teacher did that to his sister, and he had a young girl in his house then he must’ve abused her too. Maybe she viewed him as the guy who saved her from the situation, or she grew up and learned what her dad was like and despised him. She obviously wants the mc to stay alive, she was uncomfortable at the fact that she couldn’t help him.
