"These are for you." He said, handing them over to her.
Sarada gently took them into her hands, looking at him once before opening the first letter. Once she finished reading all of them, about half an hour later, she had tears streaming down her face. She turned to face him, taking his hands into her own.
"I love you, too." She said.
In the seats behind them, Sakura patted herself on the back while Sasuke began rehearsing the warning he would have to give Boruto.
