Singer IU is sending Sunny Hill her energetic support for their comeback! On January 10th, IU shared a photo on me2day along with the caption, "My Sunny Hill unnis are making their comeback this week! Please look forward to 'In Praise of the Grasshopper'. Dinggaringgaring. Dinggaringgaring. Unnis, fighting!" In the photo, the ladies of Sunny Hill and IU are seen chilling on a couch, dressed comfortably in sweats and without a trace of makeup. The labelmates posed as if they were listening to invisible headphones (though some fans began to wonder if that pose was actually in Sunny Hill's new choreography). Netizens commented, "The group photo is not complete T_T" and "Can't wait to see what they have in store!" Sunny Hill will be making their comeback with "In Praise of the Grasshopper" on January 13th. Source + Image: IU's official me2day
