They are both time traveler from modern day to help out the King in the past.

Although both are kinda over the top but the Journey to Tang is a bit (very) unrealistic compared to Splash x2 Love. They are both fun and amusing for a short movie/drama~

SPOILER ALERT! well not really but I had to type atleast 100 letters ;p

Anyway those two dramas are quite simmillar Fantasy/romance drama with a weird twist.

They're both about adults relationship (work environment) and the intimate scenes are hot af. DBaM is a little bit gloomy in atmosphere, What The Duck is funnier.
Both features handome actors.

They both entail a complicated love story a similar time period. Both have complicated love stories and fate tearing them apart. Both have militaristic and political plotlines carrying the story as well. These are both two love stories with misunderstandings and trials carrying them til the end.

Time travel with a film star assistant and a few others falling back in time. The assistant falls on top of a prince that brings the strangely dressed female home.

Eulachacha Waikiki and Twenty are both centered around friendship and brotherhood. Both are also very funny and contain a romance aspect.

Both dramas are OCN master pieces with a fair share of dark content. Don't expect too many 'nice' scenes since there are not any...

Both dramas show the story of resistance fighters in Korea in the 20th century and do a pretty good job at that.

Both dramas have a big amount of a psychological touch to it, giving an example of how the human brain can be influenced by mere wrong doings of someone else.

Very similar restaurant and food theme, there's also romance and characters involved in a love triangle.

Made by the same YouTube Channel, so they have similar vibes- it follows a group of young people and their different relationships.

Both have young youthful vibes and are novel adaptations. But I feel that MMM is more lighthearted compared to WTLOG. But watch WTLOG for a more emotional ride! Both amazing and worth the watch :)

Both about a sweet campus couple and based of a novel! They have similar happy vibes but ALSB is more light hearted while WTLOG is more emotional. But both are amazing shows that are definitely worth watching!

Love across multiple lifetimes, with leads not getting together for a long time. Couple faces many obstacles and many ghosts in order to be together.

The main leads were very much in love with one another when they were younger, however, the woman suddenly breaks up with the man and disappears from his life. Later on, she shows up in front of him and hopes to reconcile and mend his heart because of her choice to leave him.
