We previously reported that another version of We Fell In Love would be released early in June. Nothing much was known about it, and many believed that CNBLUE's Jung Yonghwa and SNSD's Seohyun would be next to sing the song. It turns out that it's not those the YongSeo couple at all, but rather, two singers that are completely irrelevant. There were rumors going around saying that the next to sing the song will be 2AM's Seulong and IU. Surprise, surprises... The rumors were indeed true as the single, titled Nagging, was released with Seulong and IU featured on the track. Take a listen to it below. http://www.youtube.com/watch?v=cGuRVo16wc4 Does this mean that there is a possibility of a new couple on We Got Married? Let's keep our fingers crossed!
