Can't find an upcoming show?

I saw on IG a poster for a drama that looks like it stars Jeon So-Min and Han Seung-Yeon that starts on the 22nd, but I can't even find a page on here about the show, and was curious what it's going to be called and about? HSY had a post where she was in a wedding dress and it said it's on MBN, but even filtering upcoming on MBN shows 0 results, so I'm lost on this show lol

It's a drama special and it's not added to MDL yet.

Added now :)
