[While Mayu was a troubled person with issues, she has her moments of empathy, one being right now. The girl sounded significantly younger than her and she can't imagine what this girl has gone through wherever she came from. She wanted to say something but she wasn't exactly good with talking to people.]

[There was a brief silence before she spoke again.]

I was never alone. I always had my sister with me. We were....close. [There was emphasis on the "close" part cause complicated reasons.]
