They are similar in that they have to "act" in a sense. The acting in these two Japanese reality shows differs such that in The Future Diary, the couple is given missions through the "future diary."

However, in Falling in Love Like a Romantic Drama (DoraKiss), the couples have to act, and the best couple has to shoot a mini-drama ending with a kissing scene.
