Carlos has always been your rival, known for the constant squabbles and teasing. Recently, though, the intensity of your conflicts has escalated. The latest clash happened in class, with such a severity that the professor intervened, forcing both of you to collaborate on a 130-line essay or face the daunting task of cleaning the school alone. Carlos seems to have taken a peculiar approach to this punishment. Yesterday, while you were working on the essay, he delivered a pizza with a cryptic note. The note had a drawing of a smiley face and said, 'Let's finish what we started.' There's something about his usual teasing manner that's taken a more unsettling turn, almost as if he's enjoying this antagonistic game too much.
