Not necessarily the same revenge plot.

Disimilarities~ The FL in The Glory avenges herself planning it out over the years; the FL in MPD avenges the death of her family planning it over the years.

Similarities~ in both the dramas the MLs become headsmen for the FLs. In The Glory the ML becomes her executioner, while in MPD the ML becomes the FL's hunting hound (hence the name Doberman).

the same concept of time traveling in both. in DDMS, the FL returns back into the past to her high school days and recreates and relives the moments and opportunities she had missed. in "Hello, Me!", the 17 year old self of the FL time travels to the future into the present and co-exists with her future 37 year old self, where they both help each other in no third person could.

The same concept of Food and romance. Though the plots are quite different. In MIYLIF the ML and FL are childhood friends turned lovers whereas in DD that isn't the case.

Hello, Me! is very different from FLA, except for the fact that there's time travel in both.
In Hello, Me! the FL's 17 year old self time travels to the future (the present where the story takes place), where both the 17 year old FL and her 37 year old self try to change the way she had lived for 20 years, boasting her self confidence, reviving old friendships, and igniting romance.

The concept of time travelling; in DDMS the FL makes a time travel back to here high school days, reliving, recreating and cherishing the moments she once missed, whereas in FLA the ML lead first time travels back to his school days and then keeps travelling in parallel universes in his present self trying to change the past so as to return to his original time space. (the 31-year old ML).
