The ethereal prelude rings in our ears, just like the fantastic and wonderful fairy world presented to us by the story The Legend of Fishing. The ups and downs of the melody, with a fantasy color in the classical, give people the illusion that they are wandering in the mythical Milky Way. Singer Kenny Kwan W. Jr. performed this song with the tone of the story hero Zhang Zhen. His natural passionate voice is full of lingering emotion, and his tenderness is permeated with firmness, such as resentment, admiration, and complaint, which vividly interprets this unforgettable love in the story.

The song Vortex was recorded in Causeway Bay, Hong Kong in January 213. In July, 213, at the premiere conference of "The Legend of Chasing Fish" in Beijing, Kenny Kwan W. Jr. sang live and met thousands of long-awaited audiences for the first time. Kenny Kwan W. Jr., who was born as a singer, was praised by songwriter Tan Xuan for her singing skills. Since Boy's Z released two new songs in the album Ready to go after the reorganization in 211, Kenny Kwan W. Jr. released a new song for the first time in two years, which is also the first time he sang the theme song for his TV series starring in the Mainland. Although Kenny Kwan W. Jr. moved to the mainland and devoted more energy to performing arts, his enthusiasm for music remained undiminished. He said in a magazine interview that singing and acting are like his right-hand man, and they are indispensable. At the conference of catching fish in Beijing, he expressed his heartfelt thanks to Mr. Tan Xuan, and then thanked him again at the Weibo, which shows that he cherished the opportunity to release new songs. We have reason to believe that he, like his fans, is waiting for another leap in music in the middle of diving.
