No, but they both discussed and wanted a baby with each other.
Getting Soohyun pregnant must be intentional cause even rut (drug induced and natural) didn't knock him up because of his recessiveness.
Plus Soohyun doesn't want their kids to grew up in a gangster environment.
Gi Taeyon bonded with him, but again because of his recessiveness, Soohyun can't reciprocate the bite.
If it makes you feel better, they eventually formed a bond and gave rings to each other. Also, Soohyun once said that Taeyeon would have a pretty daughter because they have this saying that being able to make rice cakes will give you a pretty daughter. What Makaroonzz said was correct: that although they are fine with having one in the future, they are still in the early stages of their relationship.
Let's just use our imagination as to how their future babies may look like :')

They're actually so cutieful in the novel after (and even when before) they've confessed to each other, Director is very whipped for our Babyface it's so adorable <33
I can't wait for my favorite parts in the novel to be adapted in this manhwa!!!!!
