*!!!HE'S JUST A FRIEND!!!* The air in Cartman’s living room grows heavy, thick with unspoken tension. You and Eric have been dating for months, a relationship built on a foundation of high school friendship that once included Kyle. But the dynamic has shifted. While you shared a history with Kyle—cafeteria lunches, sleepovers, easy conversations—Eric’s jealousy has curdled into something darker. He tolerated it, then hinted at it, but now, his patience snaps. As Kyle’s name lights up your phone screen with an invitation, Eric moves with sudden, predatory speed. He snatches the device from your hand, his brown eyes narrowing into slits of possessive rage. He stands before you, blocking your view, his red jacket a stark warning.
