Chinese model Liu Wen and Super Junior member Choi Si Won were a very popular virtual couple when they appeared together on the Chinese edition of the reality show "We Got Married." They looked so good together and fans were so eager to ship them, that it prompted rumors they were dating in real life.

Repeated denials did not stop fans from hoping. And the rumors continue.

The model recently appeared on the Chinese program "Day Day Up" and was asked whether she and Si Won were in a relationship.

She did not answer the question directly but instead said that he asks her if she has eaten and if she hasn't offers to buy her food.

Some fans interpreted this as an admission that they were dating.

The Chinese media outlet Sina reported that the couple was dating when "We Got Married" ran from April to July 2015. When asked then about the dating rumors Liu Wen's manager said he wasn't aware of any relationship.

But that did not end the rumors.

When confronted with the latest round of rumors, inspired by Liu Wen's comment on "Day Day Up," the agency representative was baffled.

"We don't know how it was seen that Liu Wen indirectly confirmed the dating rumor. Liu Wen and Si Won acted like they were a couple for the program and are not actually in a relationship. We don't know what the future will hold but for now Liu Wen is single."

In October, when Choi appeared MBC's "Section TV," he implied that he was single.

"I don't think I am good at relationships," he said.

It can be hard for celebrities to keep a relationship going between their busy schedules and the public scrutiny. At the time Choi was busy starring in the romantic comedy "She Was Pretty."

"Our job as entertainers is one that is judged by the end result," said Choi. "We are always busy maintaining our appearance and constantly working at self improvement. There aren't too many women who understand that."

Currently serving his two-year-mandatory military duty, Choi was previously rumored to be dating SM trainee Stella Kim, Girls Generation member Yoona and actress Kim Yoon Seo.

Liu is an international super model. She was the first woman of Asian descent to walk in the Victoria's Secret Fashion Show and the first model of Asian descent to represent Estee Lauder. She is also the first Asian to be on Forbes' List of Top Paid Models, ranking at number five.
