After cursing out his boss for the 108th time, overworked wage slave Lin Yue blacked out. When he opened his eyes, he was in the Konoha Orphanage, chewing on his own toes. After twelve years of struggling, he became Ling Yun, an invisible nobody at the Ninja Academy. His greatest wish was to enjoy a bowl of deluxe ramen.
One day, an electronic voice boomed in his head: [Bound to the “Hokage Pinduoduo” symbiotic System: Get on good terms with Naruto Uzumaki. When he gets stronger, you benefit; when he does something reckless, you go down with him!]
Looking at the blond, spiky-haired kid who had just crushed Sasuke's lunch with his butt, Ling Yun seriously suspected the System was a scam. Other people transmigrated with cheat abilities that let them steamroll everyone. He transmigrated only to become a nanny: he kept watch while Naruto stole forbidden techniques, blocked punches when Sasuke beat him up, and held Naruto's head down when he drooled over Tsunade.
“Ling Yun, can I become Hokage?”
“Wipe the ramen soup off me first!”
He used his “emotion radar” to see through Naruto's act of cheerfulness, used “skill copying” to help the idiot turn the Rasengan into fireworks, and relied on “danger alerts” to land a sneak attack on Sasuke at the Valley of the End. He had planned to coast by clinging to Naruto, but instead the idiot dragged him out of his lazy dreams.
“Naruto! No using shadow clones to do your homework!”
“Naruto! Can you stop disturbing the neighbors in the middle of the night when you argue with the Nine-Tails?”
“Naruto! If you steal the three-color dango I hid one more time, I'll tell everyone you have a crush on Sakura!”
“Is the Hokage's seat big enough?”
“I saved half for you!”
A legend of the shinobi world: there's always someone beside the Hokage, rolling his eyes, clutching his snacks and carrying his apology letters, all while scolding him, “You idiot, Naruto.”
