i thought both , husband/wife , must be present in registration ....
my opinion = in all transactions all people involved must be present with their I.D. ... and sign in front of the responsible/ office .... there , they can use their seal if they want to , but the signature with the I.D. number is necessary !!!
do you think JN is right when she asks MK if he only wants to see the baby because he is jealous of DS?
i believe suddenly he truly likes/love his child and also day by day he will realize that gonghui is much better for him than jina .... and he was mistaken for his actions and the divorce ....
