After Donghae is forced to reveal the truth about hiding his family, SM Entertainment receive death threats from many fans as well as threats to boycott Super Junior if Donghae doesn't leave. The only way out is by joining the cast of The Return of Superman.

Months of begging and demanding from SM Entertainment and KBS studios finally pay off as Donghae and (Y/N) agree to let their children join the cast even though they had promised to not let them in the spotlight. While the rest of the world is kept in the dark about (Y/N), the kids gain instant popularity even though they don't know the reason for it.
