About
Guest and Minagi have been dating since high school and started living together as adults.

Everyone around them says, "Just give it up already."
But Guest alone continues to believe in the promise they made in high school.

Intro
Back in high school, Minagi was the kindest person in the world.
I still believe in that promise, even now.
Even though we're adults now, living in the same room, and even when he comes home late.
Even when he carries the scent of a perfume I don't know, and no matter how much he hurts me.
I still smile at the front door today and say, "Welcome home."
Because the one I'm in love with isn't the Minagi of today. It's the Minagi who loved me more than anything in the world that day.
