Cheng Xiao Talks About Her Ex-Boyfriend, Fans Suspect Cha Eun-woo

Cheng Xiao Talks Leaving K-pop, Mental Health Struggles, and Past Relationship

Former K-pop idol turned Chinese actress Cheng Xiao recently had fans leaning in closer than ever as she bared a rare glimpse into her personal life on the variety show Be Daughters and Mothers 2. Joined by her mum, the show took a surprisingly emotional turn as Cheng Xiao opened up about her time in South Korea and what really pushed her to come home.

Cheng Xiao, once the centre-stage beauty of girl group WJSN (Cosmic Girls), revealed that beneath the glam of the idol life, she faced serious mental and emotional struggles.

“I wasn’t in a good place,” she shared, speaking frankly about her decision to leave group activities and reboot her career in mainland China. Her words struck a chord with fans, who flooded social media with messages of support and pride for her honesty and resilience.

But the biggest jaw-drop moment came when the topic shifted to dating — a touchy subject for any ex-idol. When asked if she had ever been in a relationship within the entertainment industry, Cheng Xiao didn’t shy away. “Yes,” she said coolly, confirming she once dated someone from showbiz. And that was all it took for netizens to go full detective mode.

She didn’t drop any names — but fans didn’t need much to work with. Before long, all eyes turned to none other than Korean heartthrob Cha Eun-woo.

“They’re Always the Ones Chasing Me” – Cheng on Love and Men

Speaking with a cheeky grin, Cheng Xiao described her ideal relationship dynamic. “I like it when they love me more,” she laughed, adding that she’s got a “bit of a demanding personality” and enjoys being spoiled. “Younger men? Not for me,” she said, shrugging off the idea entirely. Classic Cheng — bold, honest, and unapologetically herself.

In one light-hearted moment, Cheng Xiao lost a game on the show and had to message her ex-boyfriend as punishment. Much to everyone’s surprise, he responded immediately. But Cheng was quick to shut down any romantic speculation: “It was just for the show — there’s nothing more to it,” she clarified.

Naturally, the quick reply set the internet ablaze, and with a bit of nostalgia added to the mix, many fans revisited old clips of Cheng Xiao and Cha Eun-woo. 

The two once had sizzling chemistry on Korean variety shows, with one particularly iconic moment where Cha Eunwoo said “Wo ai ni” (I love you) to her in Mandarin. The clip has since resurfaced, fueling old ships and new speculation.

The Past Never Fully Sleeps

Although neither Cheng Xiao nor Cha Eun-woo ever confirmed a relationship, their on-screen banter and mutual comfort sparked rumours for years. For fans, Cheng’s recent comments felt like subtle confirmation of what they’d always hoped was real.

Still, despite the buzz, Cheng Xiao isn’t playing into the gossip. Calm, cool, and completely in charge, she’s letting people talk while continuing to chart her own path — from idol to in-demand actress, and now as someone unafraid to tell her truth.

One thing’s for sure: Cheng Xiao knows what she wants, in both love and life — and she’s not looking back.
