The First Frost (2025) C-Drama Review

A HEALING HEARTWARMING MASTERPIECE OF LOVE AND SECOND CHANCES

Have you ever watched a drama that feels like a warm, lingering hug on the coldest winter night? If you fell head over heels for the viral sensation Hidden Love, then its highly anticipated sister-series, The First Frost (难哄 / Nan Hong), is about to become your newest obsession.

While Hidden Love gave us the sweet, pure romance of Sang Zhi and Duan Jiaxu, The First Frost takes us on a more mature, emotionally intense, and deeply healing journey. Centered on Sang Zhi’s fiercely protective older brother, Sang Yan, and his high school love, Wen Yifan, this drama is a masterclass in slow-burn romance, emotional storytelling, and psychological healing.

In this comprehensive The First Frost review, we dive deep into the story overview, the stellar main cast, the electric chemistry between the leads, an in-depth ending explained section, and our final verdict on whether this romantic drama is worth your watchlist.

Wen Yifan, am I just your backup option?"

The drama opens with this heart-wrenching flashback. On a rainy night years ago, a heartbroken Sang Yan asks Wen Yifan this very question before disappearing into the downpour, leaving Yifan in tears.

Fast forward six years later. Wen Yifan is now a hardworking, quiet television news reporter trying to survive the cutthroat media industry. After a chance encounter at "Overtime"—a trendy local bar co-owned by Sang Yan—the two former high school classmates find themselves face-to-face.

To avoid the agonizing awkwardness of their unfinished past, they initially pretend to be strangers.

However, fate has other plans. Due to renting scams and unexpected circumstances, they are forced to share an apartment, transforming from estranged former classmates into reluctant roommates.

As they live under the same roof, the walls they built around their hearts begin to crumble. The nature of their relationship shifts dramatically when Sang Yan discovers that Yifan’s severe, trauma-induced sleepwalking has returned. What follows is a beautiful, slow-burning journey of mutual healing, where Sang Yan's unwavering devotion helps Yifan confront the dark shadows of her past.

THE MAIN CAST 

BRINGING BELOVED CHARACTERS TO LIFE

One of the biggest strengths of The First Frost lies in its casting. The actors do not just play their roles; they embody them with a quiet intensity and vulnerability.

ACTOR CHARACTER ROLE DESCRIPTION

BAI JINGTING (白敬亭) SANG YAN (桑延) 

Co-owner of Overtime Bar, video game company team lead, and Yifan’s devoted high school crush. Prideful yet incredibly tender.

ZHANG RUONAN (章若楠) WEN YIFAN (温以凡)

 A resilient news reporter and former ballerina carrying deep childhood trauma. Guarded, quiet, but brave.

ZHANG MIAOYI (张淼怡) ZHONG SIQIAO (温以凡) 

Yifan’s loyal, energetic best friend who provides delightful comic relief.

EDWARD CHEN (陈昊森) SU HAOAN (苏浩安) 

Sang Yan’s high school friend and co-owner of Overtime Bar.

What Makes This Drama Special: More Than Just a Romance

Unlike standard contemporary romance dramas, The First Frost elevates itself by tackling heavy, sensitive real-world issues with immense respect and care.

A REALISTIC APPROACH TO TRAUMA AND MENTAL HEALTH

Wen Yifan’s backstory is dark and heartbreaking. Having lost her father at a young age, she was sent to live with relatives where she faced attempted molestation by her aunt's brother. 

Denied support by her own family, she developed severe PTSD and sleepwalking. The drama beautifully portrays her struggle with low self-esteem and the fear of weighing others down.

THE ULTIMATE GREEN FLAG MALE LEAD

Sang Yan is the gold standard of romantic partners. High school Sang Yan was a boy who simply adored her; college Sang Yan traveled between cities just to catch a glimpse of her; adult Sang Yan is a protector. He doesn't push Yifan to open up before she is ready. Instead, he quietly safeguards her environment—baby-proofing the apartment for her sleepwalking, catching the "shadows" of her past, and constantly reaffirming her worth.

POETIC VISUALS AND ATMOSPHERIC DIRECTION

Directed by Qu Youning, the drama is visually stunning. The contrast between the warm, cozy apartment interior and the cold, damp streets of Chongqing perfectly mirrors the emotional states of the characters.

AN ADDICTIVEE, NOSTALGIC SOUNDTRACK

Much like Hidden Love had Forever Star, The First Frost features an unforgettable OST (including tracks by Mayday and Silence Wang) that heightens the emotional beats of every single episode recap.

CHEMISTRY BETWEEN THE LEADS: FIRE AND FROST

The chemistry between Bai Jingting and Zhang Ruonan is nothing short of electric. It is a slow-burn romance built on micro-expressions, lingering glances, and unspoken yearning.

They beautifully portray the transition from awkward, defensive ex-classmates to comfortable, deeply attached partners. When Sang Yan teases Yifan, his playful arrogance masks a deep-seated adoration. When Yifan finally allows herself to cry and show her vulnerability to him, the emotional payoff is incredibly satisfying. Their physical chemistry is equally potent—their intimate scenes and heart-fluttering kisses feel incredibly natural, intimate, and earned.

ENDING EXPLAINED THE HEALING CIRCLE IS COMPLETE

The final episodes of The First Frost bring Yifan’s emotional journey to a beautiful, tear-jerking resolution.

For years, Yifan believed she was a burden, carrying the guilt of her past trauma and her sleepwalking. However, with Sang Yan’s unconditional love and protection, she finally finds the courage to stand up. Together, they confront her abusive relatives, ensuring that the man who harmed her is finally brought to justice.

THE TEARFUL PROPOSAL

The emotional climax of the ending features a beautifully orchestrated proposal by Sang Yan. He sets up a heartwarming video compilation featuring congratulatory messages from all their close friends. During the proposal, Sang Yan presents a ribbon-shaped ring, symbolizing that they are each other’s most precious gifts.

With tears in his eyes, Sang Yan promises that after they marry, he will make every single one of her wishes come true. Yifan, completely breaking down her final emotional walls, declares, "I only want to marry you."

The drama beautifully concludes with a poem written on a classroom blackboard, representing their journey from high school to adulthood:

"I love everything about you—your past, your mistakes, and your true beauty. There is only one person who can truly understand your heart."

The ending of The First Frost is highly rewarding because it isn't just a happy ending for a couple; it is a successful completion of a healing cycle. Yifan is no longer walking in the dark; she has stepped into the light.

IS IT WORTH WATCHING?

If you are a fan of romantic drama recommendations that offer substance alongside sweetness, The First Frost is absolutely worth watching.

WHY YOU SHOULD WATCH IT

The "Healing" Factor: It is a wholesome, heartwarming journey of overcoming trauma.

Top-tier Acting: Bai Jingting and Zhang Ruonan deliver career-best performances.

Spin-off Connections: Finding small references and parallel themes to Hidden Love (like the protective nature of the Sang siblings) is incredibly satisfying.

Healthy Relationship Goals

Zero unnecessary misunderstandings or annoying third-wheel drama once the leads commit to each other.

WHAT TO KEEP IN MIND

It is a true slow-burn. The first few episodes focus heavily on the awkwardness of reunion and building tension, which requires a bit of patience.

The themes of childhood abuse and PTSD can be emotionally heavy for some viewers.

FINAL VERDICT

RATING: 9.5/10

The First Frost is an absolute masterpiece in the modern C-drama landscape. It successfully steps out of the massive shadow of Hidden Love to carve out its own identity—one that is more mature, emotionally resonant, and beautifully poignant. It is addictive, wholesome, and heartbreaking all at once. Prepare your tissues, clear your weekend schedule, and let Sang Yan and Wen Yifan melt the frost around your heart.
