I got a lot of same question in the comment section: "How can Baek got pregnant?" "Isn't it dangerous for him to get pregnant?" "How was his backbone?" 

And so in here I'm going to clarify something...

*if you haven't read previous chapter you need to read it first before reading this ANSWER chapter, thank you*

The previous chapter take time after 2 years after Jongsoo got his first hearing aids. The twins are now 3years old (right?) And Luhan had already gave birth to a healthy baby girl. If you noticed in the previous previous chapter, I said Luhan was pregnant and in previous chapter I mention in Ziyu's segment where he thinks that his mommy only love his sister. I think I mention that (sorry authornim couldn't remember what she wrote :p )

And as for Baekhyun, I did mention in before that it is dangerous for him to get pregnant BUT there will always have that chance. Yes he abort the previous pregnancy because it is still too early for him to get pregnant again since the incident had just happen and his backbone hasn't properly healed yet but its been years since the incident and Changmin (his doctor) had deem that he was okay to get pregnant, that is only if he hasn't felt any pain like he did before. Because he had completely healed but emm hey guys, HE'S PREGNANT BUT I NEVER SAID ANYTHING ABOUT ANOTHER BABY so emm yeah.

So for the period of 6 months he's pregnant, he hasn't felt any pain and he's pregnancy got along well. 

So
