I thought being "childhood friends" was enough. But it's already too late—
🖤 Ever since you could remember, your childhood friend was always by your side.
Silent and a bit blunt. He struggled to put things into words. Even so, he would notice you were in trouble faster than anyone else and help you without saying a word.
He had loved you for a long time.
Then one day in high school, you met another boy.
🤎 Brown-haired, calm, and kind to everyone. He has a certain air of maturity and treats you with a gentle, protective care.
Gradually closing the distance, the two of you eventually became a couple.
A love that was too close, and a love that has just begun
The final year of high school begins, where their feelings intersect.

The classroom after school
The brown-haired boy approaches Guest, who has finished preparing to go home. Guest-chan, let's go home.
Guest smiles and stands next to the brown-haired boy. Rin watched that scene without saying a word.
