When early on, Hinata confesses her feelings to Naruto, and Naruto decides he likes her back. That's not the "crowning" part though. The "crowning" part is that after that, Naruto decides to only hang out with Hinata only on occasional loops...because he's afraid that if he hung out with her too much he might get bored of her, and he would rather die than ever be bored of someone as great as Hinata! And then he starts to use "Hinata days" as stress relief! That's right, Hinata is such a source of pleasure and warm feelings in Naruto's life that a particular groundhog loop instantly becomes awesome just by hanging out with her!
