What Are The Main Characters In Once Upon A Time I Loved You?

The character roster in 'Once Upon a Time I Loved You' clicked with me because every main player feels necessary. Su Yao is the emotional heart, a quietly stubborn woman whose internal life is the real plot engine. Ye Ming is the reserved counterpart whose slow unravelling reveals deep loyalty and regret. An Rui acts as the faithful friend who keeps things grounded, offering humor and perspective, while Lu Chen is the disruptive force—sometimes antagonist, sometimes tragic foil—whose presence forces tough choices.

I also liked how elder figures and mentors show up just when the leads need to be reminded of who they are; those quieter roles give the story texture and make the protagonists’ growth believable. The dynamic between these four core characters—romantic tension, friendship, and rivalry—creates a layered emotional rhythm that stuck with me long after finishing it.

Caught up in 'Once Upon a Time I Loved You' I kept thinking about the people who drive the whole story — they're vivid and messy in the best way.

Su Yao is the emotional center: soft-spoken, stubborn in her own quiet way, with a past that colors every decision she makes. She's the kind of heroine who sketches her feelings and hides the torn pages; you root for her because she refuses to pretend she's fine. Opposite her is Ye Ming, the complicated love interest whose cool exterior hides stubborn loyalty. Their friction is the engine of the plot — equal parts misunderstanding and tender moments.

Rounding out the main cast is An Rui, Su Yao's best friend who brings warmth and comic relief, and Lu Chen, the rival whose choices force the leads to confront their truths. There are also smaller but important presences: Grandma Mei, who anchors Su Yao to family history, and a mentor figure who nudges the characters toward growth. For me, the charm is how each person has room to breathe; their flaws make the highs mean more, and I loved that about it.

On a quieter note, the main roster of 'Once Upon a Time I Loved You' is compact but surprisingly deep. At its center are Li Yan and Guo Wei: Li Yan as the resilient, internally witty heroine and Guo Wei as the composed yet emotionally complex partner. Those two drive the story, but it’s the support cast that sharpens their edges — Shen An, the loyal best friend whose humor masks fierce devotion, and Mo Xing, the charming rival who forces painful choices.

Beyond them, Elder Li (a moral anchor) and Director He (the practical antagonist) shape the stakes. The dynamics feel intentional: every supporting figure highlights a facet of Li Yan’s personality or pushes the relationship forward. I appreciate how the book treats its ensemble — none of the characters feel wasted, and even small scenes give you enough to imagine their lives beyond the panels. For me, the rich secondary details are what make the leads’ final decisions land with emotional weight; it’s subtle but effective, and it leaves a comforting ache that I enjoy revisiting.

There are a few characters in 'Once Upon a Time I Loved You' who really anchor the narrative for me, and I like to think about how they interplay like notes in a bittersweet song. Su Yao is the protagonist whose internal world is so richly textured—she’s artistic, quietly defiant, and haunted by memories that resurface at the worst times. Ye Ming functions as both counterpart and mirror: he challenges Su Yao while reflecting parts of her she can’t face, and the push-pull between them is masterfully paced.

An Rui deserves mention because friendships in this book feel lived-in; there’s history, banter, and a safety net that matters when romantic tensions spike. Lu Chen serves as the catalyst who forces hard choices, sometimes antagonistic, sometimes heartbreakingly human. Secondary figures like Grandma Mei and a certain mentor shape the protagonists’ morals and decisions, which is why the story never feels like it’s only about romance—it’s about family, identity, and learning to forgive. Overall, the cast blends realism with emotional stakes, and I keep thinking about how their small gestures land harder than dramatic reveals.

There's a warmth to 'Once Upon a Time I Loved You' that comes from its people, and the heart of the story really lives in the main cast. The central pair are Li Yan and Guo Wei. Li Yan is the quietly fierce protagonist — she’s the kind of character who carries a suitcase of regrets and tiny triumphs, practical but prone to soft, private hopes. Guo Wei is the layered male lead: outwardly steady and successful, he’s got a reserved, almost old-soul patience, but he also harbors moments where his walls crack and reveal a complicated past. Their chemistry isn’t fireworks-on-page every second; it’s those slow, meaningful exchanges and the grudging, gentle rebuild of trust that make their arc so satisfying.

Rounding out the core are Shen An and Mo Xing. Shen An is the soulmate-friend: funny, loyal, a terrible influence at times, but the one Li Yan leans on when the nights get long. Shen An’s role is crucial because she’s both comic relief and moral compass, the person who calls Li Yan on her stubbornness and pushes her toward growth. Mo Xing is more of a foil — charismatic, ambitious, and with a charm that unsettles the quieter chemistry between Li Yan and Guo Wei. He’s not cartoonishly evil; instead, he represents temptation and the alternate life path Li Yan could’ve chosen, which adds real stakes.

Then there are smaller but unforgettable figures: Elder Li, Li Yan’s grandmother-figure who offers blunt wisdom and soft cookies; Director He, the antagonist in the background whose choices pressure the leads into impossible compromises; and a few workplace friends who paint the everyday texture of the world. What I love is how each person, even in a single scene, feels lived-in — they have little rituals, small dialogues, and private jokes that make the book feel like a community rather than just a romance. If you like layered emotional beats and characters who grow through quiet choices rather than dramatic confessions, this cast will stick with you long after the last page. I still catch myself thinking about Shen An’s ridiculous one-liners and Guo Wei’s rare, honest smiles.
