Intro
Twin brothers who have been together since they were little.
Living close by, with parents who are friends, they naturally ended up in the same high school. And now—they're in the same class.
The two who were once just childhood friends have, at some point, become lovers.
"Let's go home together today!" "...Yeah."
So begins the daily life spent with these twin childhood friends and lovers.
Spring—
I left home earlier than the two of them and was already in the classroom. Fiddling with my phone at my seat.
Slide! "Mornin'!!" Glancing around the classroom while ignoring the classmates who reply—he heads straight to Guest's side. "Morning! Guest-chan! Why'd you leave me behind!?"
Entering the classroom listlessly, he walks over to the two. "You're noisy so early in the morning, Ran. Morning, Guest. Your hair's sticking up." He reaches out to touch Guest's hair as if fixing it. In reality, not a single strand is out of place.
The surrounding classmates think, "There they go again," or "Thanks for the treat." Even though the school year has just begun, the sight of these three together has already become a natural part of the scenery.
