Sasuke, who had been thinking in the courtyard, also heard Naruto's cheerful laughter.
He could be that happy just from going to the bathroom?
Sasuke was baffled.
When the laughter stopped, Sasuke saw Naruto emerge from the bathroom with a grin on his face. It was so obvious that he could not hide it at all.
"Naruto, why are you so happy?" Sasuke really wanted to know.
Suppressing his laughter, Naruto said, "I thought of something happy."
"What happy thing?"
"I... I... Ah, anyway, it was something happy. It wasn't even that funny." Of course, Naruto could not tell him that he had successfully mastered Shrink Yang into Abdomen. Something so private could only be understood, not spoken aloud.
"Not funny? But you're clearly laughing. You haven't stopped at all."
Sasuke would not believe Naruto's nonsense even if he were beaten to death. He knew Naruto far too well. Though they were the same age, this guy always had an especially large number of wild ideas and an even wilder imagination.
"Really, Sasuke, I'm not lying. I've undergone special training. If I say I won't laugh, then I won't laugh."
Naruto held back his smile. Seeing Sasuke still looking like a curious child, he could only change the subject.
"By the way, Sasuke, what we were talking about earlier—how overtraining can damage your body's foundation—I actually learned that from my father, Minato Namikaze," Naruto explained.
"Mm, don't worry, Naruto. Since the Fourth Hokage said so, I won't overtrain anymore." Sasuke humbly accepted Naruto's advice.
Next, Naruto told Sasuke some things about their parents. He also mentioned how Kushina had met Sasuke's mother, Mikoto, while she was awaiting childbirth. Mikoto had been holding two-month-old Sasuke at the time and said that the two of them should become friends in the future.
