Both are mini dramas in which the lead is an identical twin who, following their twin's death, ends up posing as the dead twin. Both leads met in school.

~ Girls coming in and getting revenge on others.
~ The thriller aspect of how those who did wrong are dealt with.
~ You slowly go through the media learning what they did wrong instead of all at once.

In both drama, both Female Lead remember their past life. But in Forever & Ever, the reincarnation part is very subtle due to censorship.

Office romance. Employee and CEO romance. Enemies to lovers. ML is the son of a wealthy family. Poor woman/rich man.

Both of the actors who played Yutaka (Inukai Atsuhiro) and Minoru (Iijima Hiroki) previously starred in this crossover movie, Kamen Rider Heisei Generations FINAL: Build & Ex-Aid with Legend Riders. If you watched Bokura no Shokutaku (Our Dining Table) and want to see these actors interact again, I suggest watching the movie. Very different storyline, but I enjoyed their characters as Kamen Rider Build/Sento and Kamen Rider Ex-Aid/Emu.

You can find Bokura no Shokutaku (Our Dining Table) with english subtitles on either GagaOOLala website or Dramacool.hr website.
