Mystery shrouds Kwon Ri Sae & David Oh’s removal on We Got Married

We recently announced the removal of the David Oh and Kwon Ri Sae couple on MBC’s ‘We Got Married’. Before today, there was no official statement addressed by the agencies nor the show on the reasoning for this removal which left many people confused.
On September 6th, representatives of ‘We Got Married‘ came in contact with OSEN to explain why they decided to remove the couple from the show. They claimed that the production team was overwhelmed in maintaining four couples and decided to stick with just three from here on out.
However, agencies of both Kwon Ri Sae and David Oh had something else to share with OSEN. Apparently, both agencies didn’t receive any notifications about their artist’s removals from the show.
MBC’s ‘We Got Married‘ is currently airing four couples including ’2PM’s Nichkhun & f(x)’s Victoria‘, ‘T-ara’s Eunjung & Actor Jang Woo‘, ‘David Oh & Kwon Ri Sae‘, and ‘Park So Hyun & Kim Won Joon‘. David Oh & Kwon Ri Sae debuted on the show back in June and have been gaining popularity ever since.
What do you think was the true reason for the removal of this couple?
