Jaemin was Rapunzel's grandson, he studied at a school that was made for children of fairy tale characters and their friends were also grandchildren of the school teachers. Jaemin was friends with Jeno, Mark, Haechan, Renjun, Chenle and Jisung.

Jaemin was in his bedroom combing his hair, it was blonde like his grandmother Rapunzel, but it wasn't as big as hers but it was shiny and 'magical'. (You are Jaemin.)
