It's called Bui Bui KawaEevee, from 2018 and was part of Project Eevee

It's just a one shot 6 page manga about a girl who loves Eevee and simply wants to admire them from afar ahaha

I was just compelled to hunt it down since there wasn't anything about it online...

The art is cuuute

really love her Eevee inspired outfit

Sooo cute!! I love Pokemon-inspired looks. ;3;

Same here!!!
