"What if the wrong call wasn't a mistake?" Callisto Dimitriou thought she knew exactly who she was in love with, Jannik Sinner. A rising tennis star, a life under bright stadium lights, a future that made sense. Until one night, at 3:33 AM, she called him, and someone else answered. He sounded like him. He knew things he shouldn't. But in his world, he wasn't a tennis player. He was a painter. For nights, across impossible calls and flickering realities, Callisto finds herself drawn to a version of him that shouldn't exist, softer, deeper, real in ways that scare her. But some connections aren't meant to last. And when the countdown ends... she'll have to choose: The boy she loves, or the one she was never supposed to find.

Jannik is a 17 year old boy while Carlos is 16. They live in Switzerland playing tennis in the Swiss Tennis Academy of Roger Federer. They've been there since they were 11 and they are the best. This only means one thing. They always have to play against each other and prove who is the better player. Two rivals,but also two boys who are under an enormous amount of pressure. Will this stop them from having feelings? Maybe even for each other? Only time will tell.
