Did anyone else notice what happened at the end of the story?

Yumi immediately changes her plans from hanging out with her Senpai to hanging out with Myuu-Myuu when she notices she having a bad day.

She goes to tell Myuu-Myuu about her crush, but after seeing her upset she sends a text off to her Senpai and then invites Myuu-Myuu out instead.

I think she's the one that has eyes for Myuu-Myuu.
