When Universe Collide

"Walk away, Yanina," he rasped, his voice dropping to a fractured whisper as a solitary tear tracked through the dirt on his cheek. "Don't stay here and watch me become the monster you already think I am." 
I didn't listen. Instead, I closed the distance between us. "What is that supposed to mean?" 
He let out a hollow, self-deprecating laugh, refusing to look up. "Let's not play games. We both know how this ends, and it doesn't involve you picking the guy who ruins everything he touches." 
"You think you have me all figured out, don't you?" I murmured. 
Reaching out, I placed my hands on his shoulders, physically forcing his rigid frame around until he had no choice but to lock eyes with me. His gaze was raw, completely bloodshot and heavy with a desperate kind of misery that made my chest ache. I couldn't stand seeing him broken. 
I leaned in closer, letting a soft, defiant smile reach my lips. "Because if you're waiting for me to run, you’re out of luck. I’ve already made my choice, bad boy... and I'm choosing you." 
One has a heart left to give. The other forgot how to use theirs. 
Yanina is a walking contradiction—sheltered yet daring, innocent yet desperate for a taste of real adrenaline. She’s stepping into the light after a lifetime in the shadows, entirely unprepared for the chaos waiting for her. 
Callum is the chaos. He’s a beautiful wrecking ball, a walking warning sign who rules the hallways by day and fights his own darkness by night. 
They shouldn't work. By all accounts, their collision should leave nothing but wreckage behind. But as the walls close in around them, they discover a dangerous truth: the person who poses the greatest threat to their sanity is the only one holding the missing pieces to their survival. 
But salvation comes at a price. As Callum's dark, suffocating obsession takes hold, Yanina is forced to confront her darkest nightmare: the terrifying reality of a boy who will tear the world apart just to keep her trapped by his side.
