It seems like EXO's D.O is fixed about his stand not to contact an ex-girlfriend after a break after he revealed in a press conference that he would never do such a thing.

According to Allkpop, D.O was asked if he would contact an ex-lover after a separation. The EXO member was serious about his stand and said, "I would never contact her. If our breakup had been clean, I'd keep in mind, "Let's never contact her again," that's why."

D.O's co-star, Chae Seo Jin, said she might contact an ex-lover especially when he is in need. However, the EXO member was upfront and insisted, "I can't do that."

D.O and Chae are currently working together in a web drama titled "Positive Physique." According to Soompi, the web drama has released its first episode on Oct. 31. "Positive Physique" revolves around the story of an ex-couple played by D.O and Chae.

The EXO member, who will be producing a major project, will seek the help of his ex-girlfriend for the film. "This project was a big challenge for me. Until now, I've always portrayed characters with emotional scars who are hurting or sad," D.O said.

He also described his character of "Positive Physique" as bright and refreshing, adding that he is working hard to portray the role in the web drama. "This is also my first time trying romantic comedy, so I was worried, but the director and my co-stars helped me a lot," D.O revealed.

D.O added he had difficulty in filming for the kiss scenes on "Positive Physique" with Chae. The idol even admitted this kind of scenes don't fit him well.

"Positive Physique" airs at 5 p.m. and will end on Nov. 4.
