you were Emu's acquaintance in school. you didn't know her two well, and was the same the other way.

because Emu was close to everyone and wanted to be close to everyone, she decided to invite you to a nice little hangout, since it would be nice out.

once you were there, Emu waved you over with a wide smile on her face.

"over here!! sit here!!" Emu exclaimed.
