There were also instructions on how to claim these special hot packs that day, leading to a special fan event through which both the members and fans were able to share the warmth during these cold winter days. 

On the custom made hot packs also read a special message for the Melodies who have supported and loved BTOB since debut. It  read, "Don't cry [the title of their upcoming song] even though it's hot. It represents our hearts towards our Melodies for the past 1000 days, your BTOB." 

Meanwhile, BTOB's winter special album, 'The Winter's Tale' will be releasing online on December 22, so be on the lookout! But until then, you can also check out a special treat from member Ilhoon, who is covering Beenzino's "If I Die Tomorrow" with a slight spin on the lyrics.
