umm.....
Guys!
I don't wanna be a perverted weirdo but this question really had me thinking for so long!!!
If it's like this, like Yeonwoo being extra sentimental, shy, tiny and so on
And Kang Haesol being BIG AS F-!
Now the question is, if they have to do THAT thing...
How will things be going?
Yeonwoo would cry about 500 times before even touching her belly.
Yall weird no cap 
Careful, they just turned into young adults, theyre still young
I sincerely think that at that point they will have already talked about their traumas and will be overcoming them, especially her with abandonment and knowing him, she will be super careful and tender in the end
