Well, they both have the marriage confusion/ cold feet thing. They both are very quirky comedy dramas.

Both are fun, light costume dramas which feature the lovely Ni Han Jin. TLBH is longer, and isn't a web series, but I think they are both good, fun dramas overall. Also, the princess in this drama has a similar adventurous spirit as the protagonist in ZGSSBGXQ.

Completely different story, but I found the protagonists in both of these to be naive, and optimistic, without being stupid and annoying, which was a very nice change. I enjoyed both these series.

Both are shorter length comedy web dramas. Both have slight romance, though STTS has more. One has dance duels, one has song duels. ?

Even though the main protagonist is a princess in TFAB, it's not that often you see female characters have a profession in a historical drama, and in both these dramas they do.

TKIAR is another Web series that has comedy in it. The plot has more romance than ZGSSBGXQ, but I think the overall spirit of these two series is similar.

Well, "Princess! You Have Five Husbands", is also a relatively short web comedy drama. I do like ZGSSBGXQ better, but they are both light, fun comedies.

Both have the same theme which is revenge .
Oldboy is a movie and it has action sequences however Black revenge is more of a drama and mainly revenge is achieved through publishing scandals.
Just if someone is interested in revenge genre , both are pretty decent to watch once.

They both get cheated on and they take away the fl son. The ex lovers wed another woman who are both the same in my opinion. To get the son back they work in hands with ex in laws enemy. To have a happy ending with a new lover.

It's got similar dynamic in which the male lead teases the female lead. Female lead has two males that like her.

In both daily dramas the sister took custody of her brother's child after the mother abandon them. An accident has changed five men and women’s fates. Unlike conventional love stories with lovely memories and anecdotes, their love is judged and frowned upon. Despite the criticisms on them, they can’t stop themselves from desperately loving each other. Bad Love is a sad love drama that portrays true love that hurts.

The mood of both dramas are similar. Warm/funny somewhat love hate but becomes love. Their romances are hidden at first and then later revealed.

Prequel of Katakoi Gourmet Nikki....is a must watch if you like Japanese or Asian foods. Hiraoka Yuta doesn't seem getting older even he almost reach 40s. I enjoyed most of Hiraoka Yuta & Motokariya Yuika drama/movies.

While completely different in plot and setting, there are some interesting similarities. Both FLs end up in a "different world" (traveling in time vs. entering a shadowy world of assassins) where they meet the ML. Both MLs are played by the same actor, and are both kind and quiet characters. Both dramas feature a focus on umbrellas and have a more unique tone and "look". The endings of both, and the ML's fate is open-ended and ambiguous but hopeful.

Is a must watch if you like Japanese or Asian foods. Hirose Alice doesn't change much even though she almost reach 30s. I enjoyed most of Hirose Alice drama/movies.
