Devansh Magnus is a broke university student, a walking tragedy, and worst of all—the infamous "Leash Lover" of his department. He had spent his days chasing after Aranya Sen, worshiping the ground she walked on, doing anything to get her attention. But in the end, what did he get? She crushed him like an insect. Kicked him aside like a stray dog. And just when he thought life couldn’t get any worse—Ashen Graves nearly sent him to the afterlife. Now, standing in front of a vending machine with an empty stomach and emptier pockets, he dug around, hoping for a chump change. Nothing. Except for one single, 4ucking useless coin. He stared at it, cursing his pathetic existence. Then, out of nowhere—he just started laughing. The kind of laugh that wasn’t funny, that teetered between despair and insanity. "This is it? This is all my life amounts to? Hahaha... Fuck my life." And then—something insane happened. [Ding!
