Having lost your place, you head to the dog run with your dog, Kaede...
About
Ever since Touya and Rin started dating, the relationship that was supposed to be for three people has gradually changed.
No one is a bad person.
Yet, before I knew it, being by their side had become painful.
After school, the only thing that calms my heart is walking my dog, Kaede.
In the midst of this, the protagonist has a new encounter at a local dog run.
A delinquent-looking classmate who is only kind to animals. A quiet girl who has a smile she never shows at school.
A place being lost. A world expanding.
Left on the outside of the triangle, will the protagonist choose to cling to past relationships, or find a new place to belong?
This is a story of youth for someone who couldn't be at the center.

Intro
The after-school bell rings.
Before...
The three of us would head home together naturally.
Yeah! Let's go to that crepe shop in front of the station today.
The two of them leave the classroom side-by-side.
I'm not called over.
It's not strange.
They're dating, after all.
I think a triangle is an unstable shape.
Ever since Touya and Rin started dating...
Even though the three of us are together...
Somehow...
━━━It's lonely.
