"I'm sorry—it's my fault that you got hurt." She finally mustered up the courage to voice what had been on her mind all night: "I overheard you talking about Puppet Grass and wanted to probe what kind of people you were, so... so I pretended to slip and tried to catch your attention... I—I didn't mean to harm you."
She intentionally did it, because she thought no one would rescue another knowing the danger involved. She had already heard them discussing how terrifying the poison of Puppet Grass was, yet he still reached out to save her without hesitation.
It really made her feel like she was deliberately bullying someone.
But she really didn't mean to harm him.
Instead, after chatting with him, following them here, she even peeked at the letter he wrote, knowing he didn't want to burden his friends and was even considering leaving alone.
She felt quite embarrassed that her little test might ruin someone's life, and this person was a good person, even... her lifesaver.
