This is just adorable.
SM Entertainment released a video of their trainees Mark and Donghyuk through their official channel to announce the opening of the SMROOKIES website.
SM Entertainment had previously released video teasers for their website, and now have opened it to the public. In the video the adorable Mark and Donghyuk bicker and joke around as they give you a tour of all the interesting things the website has to offer. There is the Staff Office page where you can individually see pictures and information about each SMROOKIE trainee. In the video, Mark even briefly introduces the Rookie Station in English.
