Man, Yuri is such a spirit animal. That insecurity of being left behind and not being important to the people important to you is such a thing. I love how this was all so subtle too. Well done on the authors part. Such a delicate and deep chapter. 
Lol. And Yuu’s unintentional back-handed comments are the best. I can’t wait to see how she and Yuri get along.
And I’ve got a feeling Tomoko’s gonna call Yuri something weird.
