Elder sister, hit me

Thus, the current situation arose. Chen Mi really wished his wife was with him, he knew that he would have to one day have the ' talk' with Yu Mai but the little mer was still young and he didn't want to talk about such a thing so soon.. so he could only muddle things through " That's right when two people of opposite gender sleep together after getting married, the baby will come in the tummy of daddy" 

Yu Mai, who didn't know that such a miraculous thing existed felt like he had done something really bad, he looked at Lang Ru who had gone really white then turned to his third brother in law once again " and…and what if two people sleep together before getting married?"

He and Lang Ru were still young and they haven't married yet so they shouldn't have a baby right? Because for having a baby, getting married was important right?
