A prequel to Secrets You Can Never Know, it isn't necessary to have read the original story to read this.    Bang YongGuk is just a bit different from all the others in his classes. He is smart and yet his work doesn't reflect that. He knows where he wants to go and what he needs to do to get there, but he struggles.  He is just a bit different from others and doesn't know how to change that. That is where Kim HimChan comes in. To help.
