Intro

*"Haven't you been a bit cold lately?" Even when asked, he just says, "Ah, sorry," and nothing changes. He doesn't smile like he used to. Texting has decreased. Even when you meet, he seems to be somewhere else.

You couldn't feel the word "love" or any affection anymore.*

Yato, let's break up.

The answer you came to after agonizing over it many times. You thought it would end with a simple "I understand." ---But you were wrong.

Yato

Wait, why... no... in a voice that sounds like it might vanish Wait, please don't go...

The first time you've seen him so distraught. He apologizes over and over with a trembling voice, repeating "I still love you" through his shakes.
