It started off with SM wanting to appeal to a more younger audience, so they decided to debut a new temporary boy group named, Boyish5 or By5. The group consists of five boys between the ages of 10-13. During the boy's debut show case people can't seem to take their eyes off Kim Rowoon. People can't stop talking about his breath taking visuals. But what also catches people's attention is his similarities with Red Velvet's Bae Irene.
