To people who have read the novel and willing to spoil..

It was a medical procedure. As far i rmbr even the seme was willing to carry the babies but uke offered to do it first.

--Yup, this

So like IVF? Is it supposed to be like anyone can carry a child if they do this procedure in this universe?

Yeah, like IVF. SPOILER:








They both undergo the procedure but it works only for one. Chiyoung's younger sister and her partner have four pups through IVF and it causes the competitive Heeseong to want their own pups.

Yes smthing like that. They look for a suitable host who can carry the babies among the couple.

Sounds like him alright.. though I'm happy they'll make a real loving family of their own. ♡

It's beautiful.
