That's not how it went. I can translate it wird to word if you wish to:
From Gutsy Ninja, Page 192:
Shu listened to her patiently, without interrupting her once.
"I have no idea what happened with Renge in the end. I just wanted to save him no matter what. But the fact is that the mountain Hyatsuki is on it's way towards us."
"You like Renge very much, right?"
"What?"
"Come on, you can tell me."
Tsuyu nodded ashamed/shamefaced.
"I can't teach the three brave ninjas of Shuku anything anymore. But I can tell you(in German "euch", by which he means all three of them) one more thing."
"Sensei..."
"Listen to me, Tsuyu. Remember this: There is a bad/evil spirit that lives in every human being. The name of this evil/bad spirit is: Ideology." Shu explained."Ideology?"
"The bad/evil spirit, that lives in Naruto, you and me, is the thought to potect Shuku no matter what."
"Yes, I somehow understand what you want to say with that Sensei."
"And in Renge lives another kind of bad/evil spirit"
"Yes"
"But which on is right no one can tell."
"What are we suppose to do then?" Tsuyu asked.
"I'll explain what you can do if you don't know what to do next."
Tsuyu nodded.
"Listen carefully Tsuyu. If you don't know what to do next, then imagine the most beautiful and happiest future you can think of.
"The happiest future?"
"Then you will find to yourself again and understand, who you really are."
"I..."
"Close your eyes"
Tsuyu did as she was told.
"What do you see? Concentrate!"
Tsuyu could see Naruto. He was and idiot, a stupid pervert, a complete moron, reckless, but still an endearing/likeable die-hard, (German word is "Starrkopf, I don't know how to translate that correct so I used dict.) who you can't be angry for too long. She met Naruto when she was six. He welcomed her with this words: "Good day, my name is Naruto. You can write a love-letter to me later. Let's do our best!"
But Tsuyu was only interested in the boy, that stand next to Naruto: Renge.
"Tsuyu" a voice called out of nowhere. "You(In German "Ihr", so it means all three again) may have failed your mission, but there is still something you(again all three of them) can do."
Tsuyu opened her eyes and shouted: "Sensei, you have to evacuate the people of the village. I will go to Naruto the fatest way!"
What I bolded is important, as this isn't making Naruto look as the silver medal. Tsuyu choosed Naruto because he is making her the happiest, not Renge. She chosed Naruto before Renge, not because she cant get with Renge.
@天地長久
There are some passages and situation in the book that happened in a similiar way in the manga, like the question of a Sensei asking one of his students if they like one spezific person (Minato did that to Obito and Sai did it similiar to Naruto). It's not far fetched to believe Kishi would do the ending similiar, just not open ended.
that is not romantic is just......friendship
