Yi San, later King Jeongjo (Lee Jun Ho) was the son of Crown Prince Sado and grandson of King Yeongjo .
So, if you want to know what happened between Crown Prince Sado (Yoo Ah-in) and King Yeongjo (Song Kang-ho) then this is the movie for you.

Same male lead actor, a coming-together romantic plot centred around a video game the two characters both play. Almost entirely fluff and sugar but super charming.

They are both game/variety show and they honestly have lots of similarities but unexpected q was canceled

Both dramas develops the relationship slowly between each episodes

Warning may be a spoilers
They both have :
-One of the main lead is ashamed about his homosexuality because of some reason.
-the other male lead discover his sexuality.
-homophobia is present but not too much.

The differences :
-there's no big age gap love by chance
-right or wrong is more focuse on family
-right or wrong is a mini-series and shorter than love by chance
-and some other differences but if like one you might like the other

They are both about the South Korean music industry. Hit the Top is more about trainee life than Imitation, but both involve both large and small companies.

Story might not be similar, but they have the same vibe:

- Both romance
- Both male leads is rich
- Both female leads from rich to poor due to bankruptcy of their family business
- Both male leads first got interest with female lead
- Both female & male lead got to live under the same roof

both have ;
time travel
changing the future by changing the past
a lovely female lead that gives a certain charm to the drama

Both movies have a similar melancholic mood and talk about the economic and emotional struggles that young couples go through.

- both have a bomber that threatens MC through a call
- high thriller/suspense genre
- villain has a "reason" for the bomb threat
- very strong main leads

First things first their way of getting along I like, It's matured and very responsible.
_both FLs are celebrities while MLs are scientists.
- The way they grow together and trust one another is amazing.
-The fact that they are together earlier and throughout the episodes we witness how they handle problems etc, instead of hundred misunderstandings and one episode of happiness.
It's how in reality most people behave and live.
if you watched one watch the other.

Both of them have strong, rich, self entitled female leads. Both of them also have the main male lead dressing up in a costume without the female lead recognizing. Both are also amazing dramas.

Well, both of the characters are similar both of the main female lead wants to join the school but the school is just for boys.

Though this one is related to e-sports instead of idols. but have the same kinda plot. you'll love it for sure

Both dramas have National Security services. Both have a master criminal that the team is hunting for, with a personal story related to the cast.

Though Criminal minds doesn't have a romance storyline, if you are looking for criminal investigation drama, Criminal minds is a great watch

Word of Honor and The Untamed are also BL series. You might like those two dramas. Dramas are about Friendship and Wars. So, if you like Word of Honor, you might like The Untamed.
