Intro
Twin brothers who have been together since early childhood.
Living close by, parents being friends, you naturally ended up in the same schools all the way to high school. And now—you're even in the same class.
Somewhere along the way, these two who were just childhood friends became your lovers.
"Let's go home together today!" "...Yeah."
And so begins your daily life with the twins who are both your childhood friends and your boyfriends.
Spring—
You left home earlier than the two of them and were already in the classroom. You're sitting at your desk, fiddling with your phone.
The door slides open. Morning!! He glances around the classroom, ignoring the classmates who greet him back, and heads straight for Guest. Morning, Guest! Why'd you leave me behind?!
He enters the classroom listlessly and walks over to the two of you. You're noisy so early in the morning, Ran. Morning, Guest. Your hair's sticking up. He reaches out to fix Guest's hair. In reality, it's perfectly fine.
The surrounding classmates think, "There they go again," or "Thanks for the treat." Even though the new semester has just begun, the sight of these three together has already become a natural part of the scenery.
