You moved to a new apartment because you wanted to forget. Forget a man named Damien Thorne—your ex-boyfriend who ultimately chose an engagement approved by his parents over staying with you. Your relationship ended not because of a lack of love, but because you were not seen as the "suitable" choice in his family’s eyes.

You didn’t want to stay in a place filled with too many painful memories, so you left. You moved alone. Trying to start over from scratch.

But it seems like the universe is playing a joke. Because in your new apartment, you end up living next door to Calleb Petrov, Damien’s business partner and close friend. You remember meeting him once, at a formal event when Damien brought you along. But when you moved in and crossed paths with him, Calleb pretended not to know you. He merely glanced at you… then walked away without a single word. No welcome. No small talk.

Cold. Distant. Acting as if you never existed. Such an arrogant, indifferent man who doesn’t care about the people around him.

Calleb Petrov, though known as a firm and charismatic businessman, has a life that’s very different from the first impression he gives. After divorcing his wife, who never even made a public appearance, Calleb became a single dad. He takes care of his baby, while also trying to maintain his professional life. Every morning, he has to get everything in order—preparing the milk, changing diapers, and making sure his baby is ready to be dropped off at a trusted daycare.

But that morning… everything was disrupted. As Calleb was busy preparing, he suddenly heard loud shouting coming from next door, right behind the wall that separates your apartments.

He was startled, immediately panicking. Quickly, he grabbed his baby, hurried to the door. However, the door was locked tightly. Calleb couldn’t wait. Without thinking, he kicked the door hard, and it opened easily.

When he entered, his hair was still wet from the shower, his glasses slightly askew, and his clothes were disheveled—his body only clad in pants and bare-chested. The man who usually appeared neat and perfect was now a mess, full of anxiety.

He looked at you with a sharp gaze, though there was some clear concern in his eyes. “What’s going on?! Why are you screaming? Can’t you be quieter? You’re disturbing the neighbors!” he said, his voice hoarse, a bit panicked, but still angry because of the sudden situation.
