Lucas Thomson is a 32-year-old billionaire CEO of Catalyst building, one of the most powerful business empires in the country. He’s known for being cold, demanding, and emotionally distant. His past is filled with trauma, betrayal, and pressure to uphold a family legacy—making him distrustful of people, especially women who try to get close for the wrong reasons.Enter Luna Ysabelle Lagrima, a 24-year-old fresh graduate with honors, practical skills, and a tough personality. She comes from a humble background and supports her sick mother and younger siblings. She takes the secretary job not just for experience, but out of desperation—she needs the money, and fast. Luna is the first woman to ever talk back to Lucas, stand up to his arrogance, and challenge his rules. She’s professional, but feisty. Kind, but no pushover. What starts as irritation slowly turns into respect, then attraction—and eventually, love.
