Here's the scene and some spoilers that I've read
Dad: "All of a sudden, "mom"? You became a mother before I knew it. Time really flies, who would've thought Mehen would become a mother."
Mom: "If you want to die, keep talking."
Dad: "That's a blatant assassination warning how thrilling."
Mom: "What makes you think it'll be an assassination?"
Dad: "Then you're going to kill me fair and square? That's refreshing in its own way."
Mom: "Stop talking nonsense."
Dad: "Who's the child's father? Is it me? So you're my wife, Mehen?"
Mom: "Do you want to die?"
Dad: *laugh* "What's wrong, honey (he used 'yeobo' here)? It has been so long since you've seen this husband, I'm hurt."
Mom: "Shut up, please."
Dad: "But when did we get married?"
Mom: "Shut up."
And as I read more about some dialogue spoilers it seems that "honey" is a regular nickname after wife
