Ni Wu took her daughter to the hospital for a consultation, and the attending doctor was her long-lost boyfriend. After seven years apart, she had long changed her name and shed the weight from her former heavy build. He didn’t recognize her—let alone know she’d secretly given birth to his daughter. Her daughter held her hand. “Mommy, why are you crying?” Ni Wu couldn’t answer. All she wanted was to turn and run. In her girlhood, she’d secretly loved him—the “unattainable flower” of S University—and somehow won his heart. A scandal had rocked the campus back then: Pei Huaiyu, the icy, snow-pure campus heartthrob, was in a secret relationship… with a chubby girl. She became the target of endless mockery. Then his cold, hoarse voice had cut through everything: “It’s just a fling. I’m leaving the country soon.” Ni Wu ended that bitter love affair and vanished. Now, their reunion shattered her peaceful life. She tried to distance herself from his world—but ended up in his bed. He resorted to threats, bribes, faking illness, even acting coquettish—anything to drive away her suitors. “Pei Huaiyu, I have a boyfriend, you know?” she snapped. Inside his Maybach, his long fingers dug into her waist as he kissed her madly. “Then let me be your lover,” he growled. “I’m richer, younger, and better in bed than him.” Seven years ago, he’d hidden their relationship. Seven years later, he begged to be her secret. She called him crazy. He told her he was actually sick.

Everyone in Beijing's elite circle knows about He Yanci’s betrothed, Wen Ruan—a delicate “porcelain doll” who’s been his fiancée since birth. Convinced he’s always found her too clingy and fragile, Wen Ruan expects their reunion to be a formality to dissolve their childhood pact. But the aloof CEO she remembers has changed: his gaze lingers too long, his touches are unexpectedly gentle, and he insists on escorting her everywhere—like a man obsessed with guarding his treasure. When family pressure pushes them into a marriage of convenience, Wen Ruan prepares for a loveless union. Yet behind closed doors, He Yanci’s cold exterior melts into tender care: he remembers her aversion to cold weather, stays up late to adjust the room’s humidity for her, and even learns to brew her favorite aged white tea. As they navigate high-society dinners in her elegant cheongsams and late-night talks that feel almost too intimate, Wen Ruan begins to wonder: Is this calculated kindness… or something real? For He Yanci, the answer has been obvious since their first meeting as adults: the once-pudgy “little crybaby” has blossomed into a woman who captivates him with every sway of her cheongsam and every stubborn smile. His “duty” to marry her was never a burden—it was a chance to claim what he’s secretly desired for years. Now, as he peels back her layers of vulnerability and discovers her sharp wit and hidden resilience, he’ll use every trick in his playbook to turn their arranged union into a love she can’t resist. From forced proximity to stolen kisses under moonlit courtyards, their journey unfolds as a slow-burn romance where secrets from the past clash with present-day longing. With Wen Ruan’s delicate strength challenging He Yanci’s controlled demeanor, and his unwavering devotion melting her defenses, this “convenient” marriage becomes a love story written in silk and starlight—proving that even the coldest contracts can warm into forever.
