Yayyy i found out how to request/suggest a couple on WGM!!!
first you need to sign up for MBC account
login.imbc.com/imbc/Login/Member.html
click agree on both then choose 'foreigner living abroad'
then everything else should be in english
if you already have one, go to this page
www.imbc.com/broad/tv/ent/wedding/request/
scroll down, you will see a pencil icon said "???" click on that to write
i think your title should be ??????? ??
then inside just write you want to see them on WGM....english is fine i think : )
wahh i'm going to write my now haha
edit : never mind, when you click to write they need to confirm your identity....
click on the link to send them copy of your passport or ID card *usually i send them pictur eof my school's ID*
