Kaede was sitting in the dining hall, eating at the table while alone, everyone off doing their own thing during the free time period, mostly just hanging out with each other while she sat and ate. She normally wasn't alone but no one had come to her for free time or to hang out, which didn't bother her much but nonetheless she was lonely

Then she saw Tenko enter the dining hall, roaming alone and seemingly not paying much attention so she stood and waved to her

"Hey Tenko! Over here!"
