Parallels between My Devine Emissary and Wonderful Fate include:
The female lead is a student who is struggling academically and is reluctant to take her tests.
She travels back in time and/or into a historical narrative, where she encounters the ML, the emperor.
The connection between the leads in both dramas is that the leads characters are quite similar in that they initially despise one another before becoming friends.

This is a Chinese BL (which was cancelled so last episodes aren't available) and has a novel
This also has non blood related brothers' love trope
I also think this drama portraits a realistic poor environment just like Unknown
Also this drama has one sided obsessive lover too

My Debine Emissary is the Chinese version of Splash Splash Love.
It's a remarke version, from the outfit the female lead wore before travel to the setting, in episode one is the same.
Yes in the chinese version we can see a full on fall out between the mom and the daughter and we had a little flash back to see the father instead of just a picture

CEO power struggle, similar family dynamics, amnesia, love triangle, wife of CEO kills him to take over company, etc etc.

If you enjoy LTHY and are looking for a compelling coming-of-age romance story, fake it till makes it is the answer. Both dramas are full of romance, temptation, flirting and capable lawyer woman. It's just that in FITMI the character development is better... both dramas are very good

the story between the two dramas has nothing in common, but the chemistry between fl and ml in miss s and love to hate you give the same vibe... sassy and mature love

Both are short series, where FL attempts to change their fates after knowing what the future awaits for them

Both have a strong FL who at one point joins the army and stands with them when the ML or SML betrays them and leaves them to die. Both have morally gray love interests for the FL who start carefree and somewhat silly and then become consumed by revenge or power and turn evil. Both have a ML or SML with whom the FL has much more chemistry but less screen time with. Both have open, ambiguous endings.

They are both Thai horror movies released in 2023 and have similar cinematography. They both contain elements such possession and black magic/curse

Both dramas show unexpected intergenerational friendships, which change the life for both sides. In Navillera - an old man and a ballet dancer, in Ossan.. - middle aged manager and his son's friend - young gay and medical student. In both cases, MLs influence each other in a good way.

Both dramas have BL elements, however they are more like background, whereas the main plot is more based on family problems, personal growths and acceptance. Fathers in both dramas try to adjust, accept their children as they are and want children to be happy.

being sibling but not being sibling ... the relationship of the main couple goes from thinking they are brother and sister and then discovering that they are not and can be in love , but the tension reminds me of the tension yuan & qian had for being in love with each other

Both are short dramas, with very good actors and interesting story.
It also have the love/hate relationship in the beginning, that leads to great chemistry!

Similar to the protagonist in this movie, the protagonist in the drama tries to take revenge before completely losing his memories.
