If you’ve been anywhere near Chinese short-drama circles lately and haven’t seen Affinity (炽热吸引) dominating timelines, then you’ve probably been offline. What started as a high-concept sci-fi romance has quickly evolved into one of the most talked-about viral dramas of the moment, thanks largely to the explosive chemistry between its two leads, Fang Jin (Gao Rongfang) and actor Cui Yuxin. Even before the drama officially premiered last month, fans were already busy shipping this pairing hard, and now, the dating rumours are following close behind.
Affinity didn’t just trend because of its intense storyline and slick cinematography. The real hook is the undeniable connection between its female lead Fang Jin and male lead Cui Yuxin. Their performances feel raw, instinctive, and emotionally grounded, making it easy for viewers to blur the line between acting and reality.
As episodes rolled out, discussions around the drama shifted from plot theories to one burning question: is this chemistry purely scripted, or is something more brewing off screen?
The latest episodes sent the fandom into full meltdown mode. A sequence filled with soft intimacy and emotional tension quickly triggered what netizens jokingly called a “national moody phase”, pushing Affinity to the top of trending lists, especially on Weibo.
One particular moment stood out, not for shock value, but for how tender and natural it felt. Viewers watched as the male lead quietly carried the female lead to bed, used his own arm as a pillow, and stayed by her side through the night.

The following morning’s gentle forehead kiss sealed the deal for many fans, with some calling it one of the most emotionally loaded scenes in short-drama history.
Unsurprisingly, a kiss scene from the drama soon went viral across platforms. But what truly impressed viewers wasn’t just the physical closeness.
It was how the characters’ emotional barriers slowly dissolved. Cui Yuxin’s typically reserved, tsundere-style character finally revealed a softer side, while Fang Jin’s portrayal balanced vulnerability with quiet strength.
The result was a relationship arc that felt earned rather than forced, a rarity in the fast-paced world of short dramas.
Fan reactions have been split but passionate. One group insists this level of chemistry can only come from genuine affection, pointing to subtle eye contact, natural body language, and behind-the-scenes clips that feel a little too comfortable.
Another camp argues that both actors are simply doing their jobs exceptionally well, praising their professionalism and ability to sell an emotionally complex relationship within limited screen time.

A third group, perhaps the loudest, doesn’t care either way and is just happy to enjoy the CP fantasy while it lasts.
Netizens have also highlighted how Affinity succeeds beyond romance. Many credit its popularity to strong character writing and a relationship dynamic that feels relatable despite its sci-fi setting.
The drama’s success is often described as a perfect storm: tight storytelling, bold concepts, and actors who fully understand the emotional weight of their roles. In that sense, the dating rumours almost feel like a by-product of how convincing everything on screen has been.
Fang Jin and Cui Yuxin are simply co-stars with incredible chemistry or something more, one thing is certain: Affinity has struck a nerve with audiences.
The drama continues to pull in new viewers daily, and conversations around the CP show no signs of slowing down. So what do you think, is this just top-tier acting, or are fans sensing something real?
