Everyone calls him a monster. Perth Tanapon, heir to the Tanapon mafia, is feared by everyone who knows his name. Cold, calculating, and ruthless, he never hesitates to pull the trigger. In his world, kindness is a weakness-and love is a luxury he can't afford. Then there's Santa Pongsapak. A walking ray of sunshine with the brightest smile, endless hugs, dramatic pouts, and a strawberry milkshake always in his hand. He's too kind for a world built on blood and violence, yet somehow he walks straight into the devil's life without fear. One accidental meeting becomes a friendship. One stolen kiss changes everything. As enemies close in and the line between love and danger disappears, Perth will do anything to protect the one person who makes him feel human. And Santa will discover that beneath the devil everyone fears is a man whose gentlest side belongs to him alone. Because even the devil needs a little sunshine.

Santa is giving birth, but there's a problem: he didn't know he was pregnant.

"Look... If I didn't know Pobmek was an alpha and you were an omega, I'd say he was pregnant!" Director Sodchuen seemed thoughtful after listening to Professor Solar, her dearest friend and colleague, pour out his feelings. "All the symptoms match." Sodchuen had expected a laugh from Solar, perhaps even a joke about her imagination, but surprisingly, the omega remained thoughtful, quiet as if trying to fit pieces of a mental puzzle together. "That makes sense..." "What?! You got teacher Pobmek pregnant?" Solar finally turned his gaze to his friend and headmistress, his eyes suddenly seeming to light up. "Of course not! But I... I might be pregnant."

Thailand, 1941. Amid the war and destruction, Perth, a military pilot, ends up crashing into the backyard of Santa's house, a rural omega who finds himself completely in love with the alpha who needs his care after his accident.

An Omega could never be number one in the world of racing, so Santa Pongsapak needs to pretend to be something he's not to maintain his position.

One was born a vampire. One was born human. Falling in love was never supposed to be part of the plan. Santa Pongsapak has lived for 118 years, hiding behind the ordinary life of a university student. He is a Pure-Blood vampire, born into one of the oldest surviving vampire families... and cursed with a dangerous gift: his voice can bend the minds of anyone who hears it. The only thing keeping his power under control is the mysterious ruby around his neck. Then he meets Perth. To Santa, Perth is a charming boy with radiant eyes, a gentle smile, and a warmth he can't seem to stay away from. And Perth falls just as hopelessly, captivated by the mysterious boy who makes his heart feel alive in ways he thought he'd forgotten. But is Perth really as ordinary as Santa believes? Because sometimes, the person you fall in love with is the very person you were never supposed to find. And some secrets are dangerous enough to turn love into a death sentence.

Perth and Santa are happily married, living with their son, Luke. But when Santa gets pregnant with twins, Perth refuses to have them-Santa nearly died giving birth to Luke, and the trauma of almost losing him still clings to Perth every single day. But Santa wants these babies. Perth: "Baby... we should abort them." Santa: "What are you saying, honey? You're kidding, right?" Perth: "I know this is a terrible, difficult decision, but-" Santa: "Are you even hearing what's coming out of your mouth?!" Santa pulled back with a disbelieving laugh. Perth: "Calm down baby... stress isn't good for you and the babies-" Santa: "Yeah! Those exact same babies you just told me to abort!" Santa pulled his hands away. "You don't want them? Fine. Never mind-I'll raise them by myself." Who's gonna win-fear or love?

Some people wear their hearts on their sleeves. Santa buried his so deep that even he couldn't tell where it ended and where he began. A friend by choice, a liar by tactics, and a mystery even to himself. Some people search for answers. Perth preferred knowing, understanding, and having things exactly where he wanted them. Nothing is hidden from him. And there was very little in this world he couldn't figure out. Very little. Some stories are built on secrets. Others are built on silence. Theirs was built on both-and sooner or later, something was bound to heal or break. And-- (?) Someone existed in the shadows. (?) Someone's someone had never been afraid of them. Neither knew that crossing paths would awaken secrets meant to stay buried. After all, some stories begin long before the first meeting.

The whole city's legal community knows Santa as "The Next Generation's Voice." At twenty-nine, he's famous for his cool, collected courtroom demeanor and a string of high-profile wins. He's the golden boy, a portrait of unwavering poise. But this perfect image is about to be shattered by a case that forces him to confront the ghost of his past. The new case seems simple enough at first glance-a property dispute. Yet, as Santa delves into the details, a familiar chill runs down his spine. The file contains names and places that trigger memories he's spent a decade trying to bury, a past filled with a love he thought he lost forever. The trauma he's suppressed resurfaces, threatening to dismantle the polished professional he's become. The real blow comes when he sees the opposing counsel. Perth. The man he hasn't seen since that fateful night. The one person who knew him completely, before the walls went up. Suddenly, the courtroom isn't just a place for legal battles; it's a stage for a painful reunion. Santa isn't just fighting for his client anymore; he's fighting to keep his past from consuming his present, all while facing the one person who holds the key to the heart he thought had turned to stone.

"Who are you? Because the more I look at you, the more I realize I'm kissing a stranger."
