"What is this?"
Sasuke gently crushed the wax-sealed pellet.
A folded ball of paper immediately unfurled.
"What's this?"
Sasuke slowly unfolded the crumpled paper.
He found it covered in densely packed writing, almost too small to read with the naked eye.
"A letter?"
Shaken, Sasuke immediately activated his Mangekyō Sharingan.
His vision sharpened dramatically.
The moment he read the first sentence, he burst into tears.
[Sasuke, my beloved girl, by the time you discover and read this letter, perhaps we will already have parted.
Ever since I came to this world, everything around me felt unfamiliar, and I was always on my guard. It wasn't until you appeared that I realized this village I hated still held someone I cherished, someone I couldn't let go of. That person was you, Sasuke.]
Although the writing on the letter could only be read with the Sharingan activated, that didn't stop Sasuke from reading it word by word.
When he realized Naruto had left this letter for him two or three years ago, Sasuke felt as though a knife were twisting in his heart.
"You're the person I can't let go of either. Naruto, I'm sorry. It's all my fault."
Sasuke wiped away his tears and continued reading the words Naruto had left for him.
[I'm sorry I hid my true identity from you. During our years together, you asked about my background more than once. The truth is, I knew who my parents were. I didn't tell you because I didn't want you to be hurt back then.
My father was Minato Namikaze. That name might sound unfamiliar, or perhaps you feel you've heard it somewhere before. He was the village's Fourth Hokage, and I am his son, Naruto Uzumaki. You always hated it when the villagers called me a demon fox.
