When Ji Sung and Lee Bo Young married in 2013, reporters asked them about their plans to have a family. At the wedding press conference Ji Sung said they hoped to start a family and that he wanted his first child to be a girl that looked like Lee Bo Young.

After the wedding Lee appeared in the thriller "God's Gift - 14 Days." Ji Sung had two hit dramas, "Secrets" and "Kill Me, Heal Me," both with co-star Hwang Jung Eum. Ji Sung's last drama ended shortly before their first child is due. And now he's focused on his future role as a father.

While the star couple has not revealed the gender of their baby-to-be, they did share the pet name they came up with for their offspring.

When Ji Sung appeared on an episode of "Entertainment Relay," he said the couple called their baby "Bo Bae."

"I hope our Bo Bae is born quickly and comes to our side," said Ji Sung.

He explained the name choice.

"It's Bo Bae. Kwak Bo Bae. My real name is Kwak Tae Geun, and so Kwak Bo Bae means 'Kwak Tae Geun and Lee Bo Young's Baby.'"

The "Bae" referred to baby.

After he wrapped up the final episodes of "Kill Me, Heal Me," the actor felt he owed his wife an apology for spending so much time away from her.

When he appeared on the March 15 episode of MBC's "Section TV," he talked about his regrets and plans for fatherhood.

"Because of work, I feel very sorry that I could not be beside her," he said. "Now that work is done, I will get ready to be a dad and go back to doing what a husband should do."

Was he planning to take time off from acting? And if so, how long would he be gone?

"Parental leave is needed, but if my wife wants me to make more money, I will have to go out to make more money, right?"

The actors met when they appeared together in a k-drama. At first she did not want to go out with him, thinking she never wanted to date another celebrity.

"I told him I would turn him down because he was a celebrity to which he said, 'Then I will give up acting.' I was tricked," said Lee Bo Young on a 2013 episode of "Healing Camp."

Even though Lee Bo Young and Ji Sung will take some time off to spend with their new baby, both of their careers are going strong.
