"You came?" "...you called" - Kim Yn is the name everyone knows - a powerful, poised CEO gracing magazine covers and boardrooms with an untouchable presence. But behind her polished exterior lies a lifetime of fear. Born with the incredibly rare Bombay O blood type and a bleeding disorder that makes even the smallest injury life-threatening, Yn has always lived on the edge of risk. Medical interventions could save her life - but she's terrified of them. Not because of the pain, but because of the trauma left behind by the one person who should have protected her. Her ex-boyfriend was a doctor. A monster in a white coat. He used her fear of needles to control her, stabbing her with injections under the guise of "help," emotionally and physically abusing her, and leaving her broken with the belief that she was too weak, too damaged, to ever be loved. Dr. Yoon Jeonghan knows what it's like to survive love that left scars. His own ex-girlfriend shattered his trust, abusing him in ways he never imagined. Since then, Jeonghan has kept his distance from anything that might make him vulnerable - especially love. But when Yn becomes his patient, everything changes. She's not just another case. She's the woman he's admired from afar since he was sixteen - a force of nature who inspired him to become a better person, a better doctor. Now, seven years later, he's finally face-to-face with the woman who once lit up his world. In each other, they find something rare - a love forged from understanding, built on safety, and healed through honesty. But when the shadows of their pasts begin to resurface, they must fight not only for each other, but for the chance to finally be free of the people who broke them. Because the strongest kind of love... is the kind that never hurts.

"I know my place in your life ma'am" - As the heir to a powerful family and living with haemophilia, Kim Ahyeon has always been carefully protected. But no one has ever made her feel safer than the boy from the orphanage. her first love, her secret joy. Since she was six, she found excuses to visit just to see him, even as the years and class divide grew between them. When he turned eighteen, her parents gave her what she wanted most, a way to keep him close. They made him her bodyguard. Now their bond is wrapped in rules and boundaries, with her love hidden behind polite smiles and professional distance. Until one day, she confesses only to be gently rejected. He says he's not good enough for someone like her. But what he doesn't realize is that he's already everything she's ever wanted. And by the time he begins to understand the weight of what he's lost, it might be too late.

"Its clear as day I married the wrong sister" - He married one sister for business. But he gave his heart to the other. To fulfill his dying father's final wish, Jeonghan gave up his reckless ways and entered a marriage built on duty...not love. His wife was kind, beautiful, and everything he should have wanted. But he didn't. Not until she introduced him to her younger sister. From the moment he met her, something shifted. The girl with quiet eyes and an untouchable soul awakened something real, something dangerous. He started treating her differently. Better. And the lines between loyalty and longing began to blur. Now two sisters are torn between love and blood. One holds his name. The other holds his heart. And Y/n knows it's wrong loving a man who should never have been hers. But the heart never asks for permission.

"i passed with a 98, its not 100%. why would I be proud?" "because you gave It your 100%, I'll be proud of you for you" - All her life, she was second place-even when she came first. Yoon Yn skipped grades, aced exams, and pushed herself to be perfect but it was never enough. Not when her older brother skipped further, achieved faster, and seemed to shine brighter in their parents' eyes. Once, they were close. But constant comparisons turned love into silence, and her heart slowly dimmed under the weight of never being "enough." Then she met him. A boy who saw her brilliance before she did. Who celebrated every little win, stood by her in every failure, and never once made her feel like she had to compete. With him, she learned to breathe. To hope. To believe again. And through him, she found the strength to rebuild not just her self-worth, but the bond she thought she'd lost forever with the brother she used to love, and the family she almost gave up on.

"I knew it was you all along, Kim Yn" - She's always been the forgotten twin-the quiet one, the spare, the shadow trailing behind a sister who dazzles. While her family fawns over her sister's spotlight, she finds comfort only in her grandmother's unwavering love. But when her grandmother is placed on life support and hospital bills mount, everything begins to unravel. Her father's business is failing. Her sister, a social media star, is engaged to a wealthy CEO in a loveless arrangement meant to save them all. But when the sister realizes her fiancé is only kind when she's not herself, she starts sending in a substitute-her twin. Pretending to be someone else was never supposed to be anything more than survival. But the more time he spends with the wrong twin, the more he feels... right. And when he discovers the truth behind the switch, he doesn't walk away. Because maybe, just maybe, he never loved the image everyone else adored. Maybe he loved the girl who was never seen.

"Do you just want to toy me around?" "Ju...You're too real for that" - She was the orphan girl no one wanted-except him. Raised in the quiet halls of an orphanage, she found comfort in the daily visits of the boy who seemed to care more than anyone else ever had. As the years passed and she turned eighteen, he begged his powerful family to let her move into their home-not as a sister, but something closer, something undefined. They lived side by side, not as siblings, not quite as lovers, caught in the tender space between. Her innocence kept her guarded. His desire, restrained. But while she clung to the safety of what-ifs, he sought shadows of her in other women. Until the truth shattered the illusion. When she finally learns what he's been hiding, she gives him one chance to prove he can be hers-for real. And this time, he won't let her go.

"Its almost over, please don't make me fake it anymore when my feelings for you are real" - She's the daughter of a powerful businessman, constantly under watch, especially by the jealous ex who refuses to let go. Desperate to escape his grip, she pulls a stranger into her world-asking him to pretend to be her boyfriend. What she doesn't know is that he's loved her quietly since kindergarten. Their fake relationship begins as a lie, but soon becomes something neither of them can deny. Until the threats become too real, and she ends it to protect the one person who's ever truly cared for her. Years pass. She leaves behind her medical dreams, choosing the business world for one reason only: to find him. When he reappears as the head chef at the hotel she now runs, everything they tried to forget comes rushing back. This time, there's no pretending.

"there's a kiss scene on stage aswell..." "I can teach you" - She's a culinary student with zero acting experience-and even less experience with kissing. So when she's volunteered to play the princess in the school play just because she's "pretty," she's already out of her depth. But the real panic sets in when she learns her role requires a kiss. A real one. In front of everyone. She's never been kissed before. Not once. Enter her brother's best friend-the guy she's secretly crushed on for years. Confident, charming, and completely off-limits. He offers to help her practice, just enough to get her through the scene. One kiss. No feelings. No strings. But practice turns into something more. One kiss leads to another, and before they know it, they're spending stolen nights together and hiding glances in crowded hallways. The chemistry is undeniable. The risk? Even bigger. Because if her brother finds out, it won't just be her heart on the line-it could ruin everything.

"let me show you how a real man treats a woman" - She was the best in the company-brilliant, driven, untouchable. But not to him. He saw her long before her heartbreak. The CEO with power in his hands and restraint in his heart, he never dared to cross the line... until the line vanished. When her boyfriend cheated-claiming her boundaries were too much-she was left shattered but not alone. Because he stepped in. He didn't just offer comfort. He offered everything. Dinners that melted stress away, gifts that reminded her of her worth, and patience when others demanded more than she was ready to give. He never rushed her. Never pushed. Just waited. Until she realized she didn't have to protect herself from him. Their connection burned hotter than she expected-and before long, she wasn't just the best in the company. She was the CEO's everything. And the whole office knew it-including the ex who let her go, now watching the woman he lost become the one everyone envies.

"I can't seem to forget you from that night" - She never meant to be there. He never meant to fall so fast. Dragged to a club against her will, a shy university student finds herself completely out of her element-until a chance encounter with a mysterious stranger leads to a night she'll never forget. He offers her safety, a ride home... and something far more unexpected: comfort, connection, and the kind of chemistry she's never felt before. She thought it was a one-time mistake. He knew it was the beginning of something real. When she discovers he has ties to her university-and worse, that he wasn't exactly single that night-guilt threatens to drown everything they shared. But he refuses to let her slip away, determined to prove he's more than his past. As fate pushes them closer through work, school, and unshakable desire, walls begin to crumble, and so do her doubts.
