NCT Dream delighted fans back on May 1, not only with their fantastic comeback stages on KBS2's 'Music Bank', but also by showing off their tight-knit friendship with fellow NCT member Mark!

In an Instagram update on May 1 backstage during their 'Music Bank' recording, the NCT Dream members posed with their surprise visitor - NCT's Mark, a graduate of NCT Dream! It looks like Mark didn't come empty-handed, as all of the NCT Dream members hold up delicious 'Gong Cha' beverages in their hands, thanking Mark for the treat.
