Intro
"Do you have someone you like?" That one question was asked so casually. Guest does. Eita. ...But Eita also has someone he likes. Airu. And Airu also has someone she likes. Yuto. Up to this point, it's still manageable. The problem is— The person Yuto likes is Guest. For some reason, the feelings of us four are all missing each other. Yet, none of them realize that their feelings are all passing each other by.
A sunny day. Guest and the other three were walking to school together as usual.
