This is not a typical story about Perth getting revenge. It is a story about two men haunted by the same past in completely different ways. Perth remembers everything. Santa remembers almost nothing. Perth believes Santa ruined his life. Santa doesn't even know he's standing on a battlefield. The tragedy is that neither of them knows the whole truth. Twelve years ago: Perth was bullied. Santa watched. Perth loved Santa. Santa never noticed. Perth nearly died. Santa never knew. Now: Perth has power. Santa has nothing. And Perth intends to use that power in the name of marriage

Perth Tanapon is a ruthless mafia boss feared by everyone in the city. Cold. Untouchable. Dangerous. He doesn't trust easily - which is why he hires Santa as his personal bodyguard. Santa is loyal, disciplined, and trained to protect. His job is simple: guard the boss with his life. But lines blur. Late nights turn into heated moments. Protection turns physical. Feelings get tangled in something that was never meant to mean anything. For Perth, it's just stress relief. For Santa, it's everything. When Santa realizes he's nothing more than a body in Perth's bed, he walks away - leaving the mafia empire... and the man he secretly loves. Only then does Perth understand the one thing he never expected to lose. Now the most feared man in the city has only one mission: Get his bodyguard back. And this time - not as a contract.

"If you're trying to intimidate me, Mr. Tanapon..." "Oh, I'm not trying. I already have you flustered." Perth Tanapon, Bangkok's ruthless real estate king, doesn't do distractions-until he walks in. Santa Pongsapak, CEO of luxury jewelry brand Muse, returns to Bangkok for his father's gala-poised, powerful, and not here to fall in love. Two CEOs. One city. The deal? Pure tension. The risk? Catching feelings. This isn't just business. It's a powerplay.

A contract marriage was never meant to include love. Cold CEO Perth Tanapon needs a spouse to secure his inheritance, and his loyal secretary Santa Pongsapak agrees to help. But between shared offices, quiet nights, and a home built by accident, a pretend marriage begins to feel real.

"Hyung!" Mingyu barged into Seungcheol's cabin, "Areum- did you hear that? She's no more." Seungcheol smirked, "I knew this would happen." "Hyung? Sorry to say this, I'm glad this happened but she was your fiance?!" Mingyu gasped, "What if some enemies of ours killed her? We need to show them our power." "Don't be sorry. I got engaged with her not because I wanted to marry her. She was just a mediator for me." Seungcheol stood up, "Second, she isn't killed by our enemies for sure. I just needed some clues." "Clues?" Seungcheol nodded, "I want the person who killed her in front of my eyes. I want to ruin this pretty devil, for sure!" "Are you talking about-" Mingyu realised. "Yes. Let's see how long he can hide his identity." Seungcheol chuckled wickedly, "I'm coming for you, my sinister love."

Seungcheol knew Jeonghan, a bit very well. It was a high school rivalry that never ended. It was dragged so bad that in the present, Seungcheol and Jeonghan even clashed in a meeting of BSK with Rose Quartz with of course an excuse. But thanks to the CEO, Boo Seungkwan, everything settled down. It was a long story to be honest and Seungcheol knew that he would recall a lot of sour memories in the following days. Because his younger brother, Choi Seokmin was going to marry Jeonghan's younger brother, Yoon Joshua. But things took a 360 degree turn when his mom revealed an unexpected proposal, for him and Jeonghan. And what will happen when an anonymous identity tries to take control of Seungcheol's life?
