The lucky attendees of Shin Hyesung's upcoming end-of-the-year concert will also get a taste of a mini Shinhwa reunion, as Hye Sung's former groupmates Eric and Jun Jin will be making special stage appearances at the show! As earlier announced, Hyesung is scheduled to host a two-day concert at Yonsei University on December 30th and 31st to wrap up the year. The concert will reportedly feature numerous collaborative stages by Shinhwa, starting off with Hyesung and Eric singing "Hello and Goodbye" together. At the December 31st concert, Hyesung and Jun Jin will also share a collaborative performance by reuniting as "The Birds" duo. A few years back, the two singers drew attention with a particularly memorable duet, eventually leading them to receive the nicknames "Mommy Bird" and "Baby Bird." It looks like "The Birds" duo will be making their comeback again through this concert. With so many big collaborations and performances lined up for this stage, Hyesung's concert is shaping up to be one of the most highly anticipated concerts this month. Source: TV Report
