Youku’s rom-com drama ‘First Frost (难哄)’ serves as the sister novel to the widely popular Chinese web novel and its live adapatation, Hidden Love, which focuses on the story of Sang Zhi’s brother, Sang Yan. The series stars Bai Jingting and Zhang Ruonan in the leading roles.

Before the cast was finalized, names like Song Weilong and Zhang Yuxi were thrown around. However, the production team ultimately chose Bai Jingting as Sang Yan and Zhang Ruonan as Wen Yi Fen.

The official announcement of the cast generated significant buzz on Weibo. Audience reactions were mixed, with some fans expressing surprise at the casting choices. Many fans who had watched ‘Hidden Love (2023)’ were hoping for Victor Ma to reprise his role as Sang Yan, but were disappointed when it was announced that he wouldn’t be playing the part.

For Those Unversed: Hidden Love (偷偷藏不住) is a 2023’s popular youth rom-com starring Zhao Lusi and Cheng Zheyuan. This series not only captured domestic audiences but also massive international viewers due to its lead’s magnetic natural chemistry and love-filled, airy fluffy plotline.

In the series, Zhao Lusi stars as Sang Zhi who has a crush on her elder brother, Sang Yan’s (portrayed by Victor Ma) best friend Duan Jiaxu (played by Chen Zheyuan).

Hidden Love focuses on the relationship between Sang Zhi and Duan Jiaxu. First Frost, on the other hand, centers around Sang Yan (Sang Zhi’s elder brother, Duan Jiaxu’s brother-in-law). So, First Frost is the parent story of ‘Hidden Love’ or a spin-off of it.

Well, it is understandable that some audiences might find it quite strange about the casting choices. In Mainland China, it’s pretty common that they do not stick to the original casting when they adapt new stories into live-action, even if the story is set in the same universe, timelines or characters are overlapping.

Also,’The First Frost’ production team is different from Hidden Love. So, there’s a high probability that there might be significant differences between these two productions. What I meant by saying this is, that the type of Sang Yan we saw in Hidden Love might be slightly/completely different in First Frost including his physical appearance to personality.

So, here we’ll be looking into some major plot highlights of this upcoming rom-com series. Are you curious about what kind of story you’ll be getting to watch in the series and other interesting facts related to it? If Yes, Keep reading!

Sang Yan (nickname Jiang Shuang) is a department manager and one of the owners of the Bar. He is smart, kind, super handsome, and has a practical mind. He is a bit eccentric and because of this, he has a limited number of friends.

Doubts To Cheers: Live Adaptation Surprises Fans

Initially, the announcement of the main cast elicited mixed reactions from the audience. Some expressed doubts about the pairing, saying it lacked promise. They argued that Bai Jingting doesn’t possess the necessary charisma to portray the male lead, Sang Yan, while Zhang Ruonan, though pretty, doesn’t quite match the description of Wen Yifen in the original novel.

Even though there was a lot of skepticism about this pair before filming, after seeing some Reuters and video clips recently released on the internet from the filming site, fans seem to have changed their opinion.

In the latest Reuters release, Bai Jingting and Zhang Ruonan were spotted at the supermarket. Fans are pleased that the live adaptation maintained the original style. From clothing to hairstyle everything closely resembles the Manhua, with only minor alterations like female protagonist Wen Yifan having bangs in the drama, which is different from the source material where the female lead does not sport bangs.

Given the fact that Bai Jinting has always had good chemistry with his female costars and is often counted in the list of one of the best actors,The First Frost is expected to be another successful addition to his list of credits .Those who have watched Bai Jingting’s previous projects like Reset, You Are My Hero, New Life Begins, Destined, and etc, are more familiar with Bai Jingting and his performance ability.

On the other hand, Zhang Ruonan, a rising star in the industry is doing well in her acting career. She’s been mostly active in modern rom-coms. Due to her warm, sweet, and cute appearance, some audiences think she’s fit for the role. Earlier this year, she appeared in ‘My Boss‘ which was well received by audiences starring alongside Cheng Xingxu.

Supporting Cast of First Frost

The complete cast lineup has not yet been revealed. Many fans are saying, it would have been better if Zhao Lusi and Chen Zhe Yuan would have a cameo on this one. The duo portrayed the leading characters, Sang Zhi and Duan Jiaxu in Hidden Love where audiences deeply fell in love with their undeniable chemistry.

In addition to the main leads, the supporting cast includes Zhang MiaoYi, Zhai Xiaowen, Edward Chen, and others.

If you haven’t watched ‘Hidden Love’ yet, I highly recommend checking it out. Meanwhile, ‘First Frost’ has just completed filming and is expected to be released in 2025, so there’s a bit of a wait. While waiting for First Frost, you can enjoy ‘Hidden Love’ on Youku.
