Sang-Jun is a talentless idol trainee. The day his director spoke to him about transferring entertainment companies, Sang-Jun received the book "The Law of 10000 Hours," and unlocked access to the "Talent Library." "Voice from Heaven" and "Flexible Dance Machine" are some of many talent books he borrowed from the library to gain talent. Great, with this talent I'm going to become a top star!
