Both stories follow two men as they struggle to prove their innocence in the Japanese legal system against all odds.

Both are dramas about people who are honest and kind, who have to cope with hardships, that they don't deserve...and do it not changing, being always the same kind and friendly people, who care about their families and friends more then about themselves...

The Main lead in both shows are wrongly accused of a crime they didn't commit. Smile focuses more on the process of the trial, while Nigeru Onna focuses more on the emotions the Main goes through after she's released.

Their are similar because in both of them a man with a kind heart that had a bad past has been convicted wrongly. Both of them don't want to hurt their lovers.
