One of subplots in Enjiya is quite similar to the main plot of Bad Family - a group of strangers forms a foster family to take care of a little orphaned girl

Both the drama's Protagonist's go through thick and thin to understand what love is and whom they love.

Its a "sequel" per se that most members of HS season 2 and some members of HS season 3 reunite and interact together. For those who are heartbroken with the "famous couple ship" in season 2, this is a must show for closure and happier endings. :)

Both have strangers who are non-celebs that cohabitate in one house and they date while doing missions. Both are reality shows with panels discussing the interactions of the non-celeb participants. Though Love catcher has an added spice since not everyone is in it for love... some for money. So the panel and participants have to guess, which makes the show more interesting.

Both series are sweet reality dating shows with the participants living in the same house and interacting while doing missions. In the end they would choose the partner that they like. The only difference is that in Love timing, the participants are non-celebs and there is a panel that discusss the interactions. While in Idol and Romantic, korean idols are the participants.

Love timing has the same concept as Terrace house, a Japanese reality dating show about strangers living in one house. If you enjoyed one, you will most likely enjoy the other. Both shows also have more than one season to enjoy.

Love timing has the same concept as Heart signal. Heart signal has Korean and Chinese versions and has 3/4 seasons. My favorite would still be Heart signal Season 2 Korean. Watching the first season of Love timing reminds me of that heart fluttering while I support my fave couple on both series.

Both have creepy horror vibes, but fun to watch.
Unpredictable plots.
Leads with special powers.
The romance is not fluffy at all.
(both plots are the kind only Jdramas can provide really)

Both shows feature found family composed of lonely people that came together because of their unlucky lives

-Similar relationship trajectory between the King and Queen. He hates her initially to the point of endangering her life but grows to be a devoted partner in crime
-Both MLs show cowardice and incompetence but in one case it is an act
-Scheming mother in law and love interest. In the Last Empress the character flaws are extreme
-Tough female lead
-Choi Jin Hyuk is in both the dramas and plays an ally to the FL in both!

Both drama have:
Relationships that blossom from random meetings, fashion, the theme of stepping out of your bubble and comfort zone and finding fun in places you didnt expect.

They are similar in some parts.
The ML is a widower and has kids and is older.
the FL helps with the kids.

In Don't Disturb My Study, FL shifted classes from existing class to a new class after a long time while ML does the same in The Big Boss S2. In DDMY, the group of friends cheer FL all along, while the same happens with ML in TBB S2. In both dramas, the leads build a strong friendship and bonded closely with their existing class very much.

Wudang sect as the central of story. many characters have similar name and characteristic and traits.

In both dramas there is a man who is decieved by the woman he loves.
In both the woman wants reveange
In both the man is rightous
In both there is a second lead woman who wants the male lead to herself
both with somehow the same vibes

#secret is more romantic than F&F
