CNBLUE’s Jung Yonghwa and SNSD’s Seohyun finally revealed the final process to the creation of their couple song on this week’s MBC’s “We Got Married.”

They had earlier received a mission asking them to create a couple song, so Yonghwa took charge of the song’s melody, while Seohyun added lyrics, creating a perfect harmonization.

Surprisingly, on the episode aired on December 1st, it was revealed that Seohyun actually didn’t play the guitar in the UCC video.

Although appearing to be strumming the strings in the actual video, Seohyun explained her secret stating that she was actually strumming in the air and that Yonghwa was the one performing everything.
