"Robbie, we've had this conversation twenty times since we broke up," Wendy sighed. She sipped her blue raspberry slushie and licked her lips. The dye stained them to a faint arctic blue.
"Since you broke up with me," he corrected.
"Dude, that still counts as us breaking up, even if it wasn't mutual," she said. The redhead turned on her heel to walk away, but he seized her wrist.
"But... I love you more than anything. I want another chance," he said. Tears lurked at his eyes, threatening to fall down his face. His skin was usually the color of porcelain, but the emotion welling inside of him turned his face a bright scarlet. Wendy wiggled to escape, but his grip was firm. Tight. Strong.
"Let go of me! I wouldn't give you another shot unless you were the last person left in Gravity Falls." When he still did not let go, she dumped her slushie on his wrist. He winced from the freezing pain, forcing her release, and she bolted away.

"Hey, kid. Where's Wendy?" He scuffed his Converse on the bare floor of the Mystery Shack, with no regard for the streaks of dirt that were left on the floor.
"She's not working today. It's none of your business anyway, Robbie!"
"Guess it's not. Gotta ask another question though, what's with that weird book you always carry around? The one that you're always talking to Mabel about. You constantly check to see if it's still there." The boy's eyes widened and he clenched his teeth, breaking into a cold, flustered sweat.
"Huh? Book? What book? Hehe, I don't know what you're talking about."
"C'mon, hand it over. I'm really not playing around today."
"I said that I don't kno—" Robbie hooked Dipper in the temple with his fist, sending the young fellow into a dizzy flurry of pain. Again and again the teen beat on the boy, who had been quick to black out, making Robbie's job quite simple and rather quiet. He glanced around, with no Mabel or Soos or Stan nearby, then pocketed the journal and left.

In Robbie's room, a teen boy sat crosslegged on his bed with a thick book on his lap and a lit coal-colored candle in his right hand. He flicked through the stained pages to find something, anything that can make Wendy's heart belong to him.
And finally, he found it.
