He Kept His Oath, She Kept the Pain
Zhou Sheng Chen, a prince raised within the palace yet forged on the battlefield, grows into a loyal and formidable general devoted to protecting the realm. Cui Shi Yi, born into the prestigious Cui family, is promised to the Crown Prince from birth, but her fate shifts when political tides turn and her betrothal is reassigned. Stripped of her voice after a childhood trauma, she returns to a capital simmering with unrest, where power struggles dictate every move. To ease tensions between their families, Zhou Sheng Chen takes Shi Yi in as his disciple and brings her to his estate in the Western State. Within the quiet walls of the manor, a tender bond begins to form between master and pupil, but their connection is constantly restrained by duty, loyalty, and the ever tightening grip of palace politics.
Right from the start, One and Only sets the mood with tension so thick you could slice it with a butter knife. It practically whispers, “This is going to hurt,” and somehow still lures you in like a moth to a very tragic flame. The opening political maneuver involving Shi Yi’s broken engagement already adds weight to the story. It is the kind of move that makes you sit up and think, oh, we are not playing around here. And just like that, I was hooked. Shi Yi’s childhood arc is where things feel a little shaky. Her transition into muteness after her father’s sudden departure feels more like a dramatic shortcut than a fully earned emotional breakdown. The setup had potential, but the execution lacked depth. The young version of Shi Yi, played by Liu Qi Qi, was expressive and did her part well, which makes it feel more like a writing issue than an acting one. The moment itself felt rushed, almost like the drama pressed fast forward on what should have been a slow emotional spiral. Then enters Zhou Sheng Chen, portrayed by Ren Jia Lun, and suddenly everything feels heavier in the best way possible. His introduction on the battlefield is commanding, setting him up as both a protector and a potential threat. A prince who could easily claim the throne yet chooses loyalty instead? Classic recipe for pain. His oath to never marry or have children is the kind of decision that screams future heartbreak, and I felt that anxiety settle in immediately.
When Shi Yi, now played by Bai Lu, arrives at the Western State, the story slows into something softer, almost deceptively peaceful. Their dynamic as master and disciple is both heartwarming and quietly amusing. Zhou Sheng Chen, a brilliant general, suddenly feels like a clueless teacher, while Shi Yi is proactive and earnest. Their interactions are gentle, filled with curiosity and an unspoken pull. That said, I could not help but question a few things during this phase. Everyone somehow understands Shi Yi’s sign language flawlessly, which felt a bit too convenient. And for a student teacher setup, there was surprisingly little teaching going on. It almost felt like the whole arrangement existed purely to let their relationship bloom, which, to be fair, it did beautifully. The timeline, however, can get a bit confusing. The frequent flashbacks blur the sense of progression, especially when it comes to their emotional development. After spending what feels like a relatively short time together, their reunion after 19 months carries the emotional weight of a long lost romance. It left me wondering if I missed a few chapters somewhere. But then again, distance makes the heart grow fonder, or in this case, absolutely wrecked.
And wrecked I was.
The ending of One and Only is not just tragic, it is soul crushing. Zhou Sheng Chen, a man who spent his life protecting others, meets his end not in glory but in unimaginable cruelty. Accused of treason and subjected to brutal torture, his fate feels deeply unjust. I was beyond frustrated, the kind of frustration that makes you want to argue with fictional politics. Shi Yi’s reaction is where the emotional damage truly peaks. Bai Lu delivers a performance that is nothing short of devastating. Her silent grief, the kind that does not scream but suffocates, hits harder than any dramatic outburst. And when she finally makes her choice at the end, it feels both inevitable and painfully justified. That final moment broke me in ways I did not sign up for.
The strength of this drama lies heavily in its emotional restraint and the performances of its leads. Ren Jia Lun brings a quiet charisma to Zhou Sheng Chen, embodying a man who loves deeply yet chooses duty every single time. His affection is subtle, expressed through small gestures rather than grand declarations, which somehow makes it even more impactful. He is the definition of “if he wanted to, he would,” except he will not, because he cannot. At the same time, his unwavering selflessness can be frustrating. There were moments where I wanted to shake him and say, please, just be selfish for once. His refusal to seize power, even when it could have prevented so much suffering, feels noble yet painfully naive. It is a character flaw that adds depth, even if it tests your patience. Bai Lu, on the other hand, surprises with her portrayal of Shi Yi. Known for stronger and more assertive roles, she fully transforms into someone soft, timid, yet emotionally resilient. Shi Yi’s love is quiet but unwavering. She does not fight fate, she walks alongside it, accepting her role while holding onto her feelings. There is something incredibly refreshing about a character who does not try to rewrite destiny but instead finds meaning within it. Their chemistry is, simply put, magic. No grand romance, no excessive physical affection, yet every glance feels loaded with emotion. Their relationship is built on restraint, which makes every moment they share feel precious. It is the kind of love story that lingers, quietly haunting you long after it ends.
The supporting cast adds warmth and dimension to the story. Zhou Sheng Chen’s disciples bring a sense of found family that balances the heavier themes. Their bond with Shi Yi is endearing, like protective older siblings rallying around their little sister. Among them, Xiao Yan, played by Zhou Lu La, stands out with his calm and playful presence, adding a touch of lightness to an otherwise heavy narrative. On the darker side, the villains leave a strong impression. Qi Zhen Zhen, portrayed by Liang Ai Qi, is as unsettling as she is effective, while Liu Zi Xing, played by Wang Xing Yue, is a walking bundle of anxiety. His character feels like a ticking time bomb, unpredictable and deeply disturbed. While his obsession with Shi Yi raises some questions, his presence undeniably heightens the tension.
Visually, the drama is stunning. The cool toned color palette enhances the melancholic atmosphere, making every scene feel like the calm before an inevitable storm. While the CGI occasionally breaks immersion, the overall aesthetic remains pleasing. The OST complements the story well, with tracks that linger in your mind long after the episode ends.
In the end, One and Only is not just a love story. It is a story about restraint, sacrifice, and the kind of love that exists even when it cannot be fulfilled. It hurts, it frustrates, and it stays with you. This is the kind of drama that does not just break your heart, it keeps the pieces as a souvenir.
