Heechul openly shared the stories of his past relationships on the Feb. 11 installment of "Knowing Brothers." The Super Junior member even looked back on how he broke up with his then-girlfriend while having their first movie date.

According to Koreaboo, Heechul and his then-girlfriend were watching "Lion King" in a DVD room when the former was forced to end their relationship. "She would continuously keep touching me. So I told her that we should stop meeting each other," he said.

The Super Junior member admitted he was still naïve back then, revealing that he has not even experienced his first kiss during that time. He also added that it was his first time to be in a DVD room.

Heechul went on, "I was immersed in the story of "Lion King" but she kept touching my side. I was angry and wanted to break up with her."

After sharing his breakup story, Leeteuk joked about Heechul's experience and said his co-member was just scared that his then-girlfriend would hurt him at that time.

Previously, Heechul also shared how the Super Junior members would open up when they like someone. Allkpop reported the idol bluntly said all of them have different tastes when it comes to women.

The 33-year-old singer added they usually inform each other when they like someone or started dating. "When we get a girlfriend, we always tell the [Super Junior] members because there can't be any overlap," Heechul said.

Not only that, the Super Junior member also shared one of his strategies in winning a woman's heart. During his trainee days, Heechul courted a girl by singing to her over the phone.

He added most of his co-trainees inside the dorm would even stare at him in disbelief. "Donghae would walk by and comment, "What the hell is he doing,"" Heechul narrated.
