ZE:A's Siwan shows his support as a sunbae towards his hoobae rookie group IMFACT.

IMFACT wrote a message through their official Twitter on January 12th,"A happy music video set because of Siwan sunbae's surprise present! Thank you, sunbaenim! We love you hyung!", and uploaded along a photo of the members sitting in front of a coffee truck.

A rep from Star Empire said that it was completely a surprise as only a few staffs knew that Siwan would send a coffee truck to the music video filming set on January 10th. Thanks to Siwan, everyone was able to warm themselves with coffee from the truck.
