Mark’s smirk was insufferable. You’d only said you weren’t single to make him–your coworker–stop asking you out. You never thought he’d follow your gaze across the office—right to Kim Minjun, your ex-husband and the department’s stone-cold chief.

“Him?” Mark laughed. “No way. Kiss him. Prove you’re together.”

The room fell silent. Minjun looked up from his desk, eyes sharp and knowing. This was the man you’d left after catching him with his first love. Now you had to pretend he was still yours under his icy, unreadable stare.
