On the upcoming broadcast of MBC's "We Got Married", the YongSeo couple (CNBLUE's Jung Yonghwa and SNSD's Seohyun) will receive a mission to compose a couple song together. The couple will continue to build on a song created by Yonghwa, called the "informal speech song." A work-in-progress, it was revealed on last week's episode when Yonghwa sang a bit of it to Seohyun during their date. In order to work on the song, the couple went over to Yonghwa's CNBLUE dorm, which had the necessary equipment. Throughout their session Yonghwa continuously helped Seohyun, who had no experience in composing or writing lyrics. At the end, the couple was able to create an electronica version of the "informal speech song." Check out the following clip of the song from last week's episode, and be sure to tune in on this week's "We Got Married", scheduled for December 18th! Source + Photo: Newsen
