Go Jun Hee apparently threw 2AM's Jinwoon in for a loop with a cold text message! .

Last week on 'We Got Married', the actress prepared a surprise birthday party for her onscreen husband and invited his idol best friends from the '91 idol line, SHINee's Key, KARA's Nicole, and MBLAQ's Mir. But Jinwoon didn't look too happy upon walking into the party, leaving everyone wondering what put him in a sour mood.

It was later revealed that Jinwoon received a text from Go Jun Hee the day before which read, "Let's not contact each other personally." So having received such a text, throughout the celebration, Jinwoon seemed more worried than happy. Thus, he was even more surprised when Go Jun Hee happily presented him with a cake that she helped make on last week's episode.

Find out why Go Jun Hee had sent him that text message on the 18th's episode at 5:05 PM KST!
