they're both about time travel or connection with the past and or the future

This two dramas are very similar. The main couple they are from rival countries. She saved his life when they were kids. Both main girls have something they wear to make the male lead recognize the girl, in general and I it was a jade hairpin but in The King's Woman it is a half cirlce jade necklace. The male lead forces marriage with the main girl. The main girl is in love with someone else in the beginning. The only difference so far is that the main guy is king in this drama but in General and I he was a general, also the female lead was a female strategist in General and I but in this drama she is a swordfighter.

it might be interesting to see for a fantasy fan. a lot of magic and good romance.

the main lead is from a fantasy world.
he also has superpowers
the plot is interesting

i believe it will be interesting to watch as there is a mix couple as in The Bride of Habaek. Though the fantasy character is a girl.

Similar concepts of living together with genius male lead and carefree female lead. Both slice of life dramas set in school, with sweet romance. It Started With a Kiss is the classic retelling of manga Mischievous Kiss and has a similar story to Attention Love regarding the relationship between the two leads. If you enjoy Attention Love you will definitely enjoy It Started With a Kiss and it's sequel They Kiss Again.

Both are 100+ episode revenge dramas. Plots are similar: death of a child, stealing of husbands/boyfriends, etc.

Both are time-travel drama because of their first love and the guy is trying to change his destiny and make the girl love and marry to him.

Both dramas have a similar type of genre with cute and passionate romance alongside with actors portraying a similar role. The male lead here is a prince, meanwhile in Novoland the male lead is a Emperor. Their personalities are very similar as well. Although Novoland has a bit more of a high fantasy plot, both are definitely light and easy to watch dramas!

Both have an element of mystery and tell an engaging story through the use of two different but interrelated time periods.

Both are adapted from the same novel. So, for those who are
interested in the chinese remake, you can try the taiwanese one : it should give you an idea of the new one

Adapted from the same novel. but beware : they're both REALLY different (and the movie is not half as good as the drama)

Both female leads are blamed for the death of the male lead's girlfriend. But in Secret, the female lead doesn't really killed the girlfriend of the male lead, she just took the responsibility for what her fiancee did. Also, both aggressive male leads.

They both feature the theme of food. If you love this drama then trust me, you'll love I Order You. It gives you the same vibe.

Both thrive on the adventure of ancient artifacts and brotherly relationships.
