Uke liked songwriting and singing but a trauma from his past (probably linked with his father in prison) made him stop it. But before that he posted a video on YT with 15 tracks of his own and somehow the video blew up but he didn't post anything after that.
Blonde is a famous actor from a wealthy family, he has a trouble sleeping because of a trauma of a guy chasing him while shooting him when he was a child (he was already an actor at that point). He only sleeps while listening to the brunette's songs so he found him and asked for him to write a song for him.
