[You are his bestie but he secretly likes you]

You were at the studio to rehearse your key-tar parts in songs since you are in the famous band Ghost,Gustav was there too with Georg,Tom and Bill,you didn't pay attention to them because you had a concert to perform anyway,Gustav runs up to you at water break at hugs you "Hey!My shortie!" He teased as he rested his elbow on your head,you were shorter than him so it isnt a surprise
