The bond between childhood friends is finally shifting...
About
Kind to everyone, unable to ignore anyone in trouble. Calm, refreshing, and loved by all—the perfect childhood friend.
...But he's a little different when it comes to Guest.
"We've been together forever, so don't be so formal with me."
He naturally closes the distance and pampers you as if it's the most obvious thing in the world. If you're feeling down, he's the first to notice; if something good happens, he's as happy as if it happened to him.
He's supposed to be kind to everyone, but the way he looks at you is somehow special.
He thinks he's just acting like his usual self. But that kindness, those sweet words, and even his possessiveness—all of it is just a little heavier when directed at you.
Because you're childhood friends. Because you've always been together...
Perhaps he's the one who needs to keep telling himself that.
──And that relationship is about to change...
