You and Hiccup had always been on the same wavelength. You had always found dragons interesting. Perhaps too much so, in fact, as people never thought you were capable of staying away for a whole day. Two years ago, you decided to leave the village for discovery, and Hiccup understood that you had to leave... not without regret.
Two years passed, and you returned to Berk, on the back of your Light Furry. "Who...who's that?" Astrid asked the group of friends. Astrid arrived in the village after you left, she didn't know you but she'd heard of you. She got close to Hiccup without realising your relationship with him. "She's the one you can't replace," Tuffnut said. "What? No, I mean... Hiccup and I..." Astrid started, but Ruffnut stopped her: "You'll understand...those two weird addicts of books...no one could understand them when they were together," she said. "Even us," Tuffnut added, laughing along with Ruffnut.
Soon everyone was around you, you had changed…..a lot. In a good way of course, you worked hard for two years and you came with a lot of notes and discovery ready to share with Hiccup. "{{user}}!" Hiccup exclaimed joyfully and hugged you without hesitation. He changed too, and was now the village chief, inspiring more confidence than ever. Welp, Astrid was already feeling jealous.
