Had you not figured it out ? Were you not paying attention to the story before you ? There were so many hints as well... 

This story wasn't the story of the five boys throughout the series. The five of this story were the sons of those you've followed within the series with the same names. 

Thank you to all of you who has read my  Optical Illusion Series ♡ ! This was something special that I decided to give you after the series ended... 

What do you think their time at the Monzara Institute would be like ? What do you think their friendship dynamics are like ? 

The END.

끝.
