Bo,
They met when she was working a summer job during the summer after her first year of middle school. At the time, they weren't really close because she only worked there for a week; her family felt the place was too far away and nobody was looking after her, so they told her to quit and go work at a relative's place instead.
Later on, they chatted casually on QQ, grew closer, and even talked on the phone.
