Both have very smart female leads.

In The Glory, FL returns from her adoptive family to her own house to seek the truth.
In Coroner's Diary, FL disguises herself as another person and enters their family to seek the truth.

In both dramas, the ML is influential and is helping the FL with her plans and revenge.

Both dramas are of dark themes

One is obsessed with the other ......................................................................................................................................

Boxer male lead _____________________________________________________________________________________:))

Scheming. Lots of it.
The female leads are smart and help the male leads in plotting.
Major palace setting. Power play, politics, conspiracies, etc.

Personally, I love the main actors of both dramas. All four of them act so well, and they do justice to their characters, especially in historical dramas.

The plots look so similar.
Jiang Shan Wei Pin has not been released yet. But the whole 'being the stepping stone for each other' sounds like The Glory.

They both help each other for their own benefit. Scheming and plotting.
Smooth-talking and cunning female lead>>>>

-- one is a drama, and the other is an idol TV show
-- both revolve around babies
-- characters learn to take care of babbies and understand their need and lifestyle
-- Our Universe, since it's a drama, has more plot too

If you love watching babies, you'll love this show.

-sharing a house
Both dramas' main leads share a house.

- working environment
The main characters work together

-starts off on the wrong foot
In both dramas, the main leads are strangers, and from the beginning, they are not on good terms for (kind of) silly reasons.

-smart and ambitious FL, rich & renowned ML
FL is hardworking, smart and chasing her goals. ML is already renowned in their field and comes from a rich family.

-banter and comedy
Both dramas have a fair amount of funny moments and have a lot of bickering, too.

Both are pretty feel-good, comfort dramas. Hope you guys enjoy these ?

I feel like LHF is a lighter and funnier version of The First Frost.
TFF is emotionally very heavy and represents trauma and its effects. LHF isn't that emotional (yet).

The main characters of both dramas share a house.
They start off with banter and bickering, but then slowly get comfortable with each other.
The characters understand each other very well.

Both Yifei and Sang Yan come off as cocky, silly, and maybe a little arrogant, but they're actually caring and kind-hearted.

Yes, these dramas have more differences than similarities, but I find them both easy to love and comforting. Hope u guys love it too.

- FL & ML helping each other
In both dramas, the main leads are helping each other in finding the truth, bringing justice, and planning revenge.

-smart main leads
Both dramas have characters who have depth, are intelligent, and are working towards their goals.

The romance isn't overshadowing the plot at all. There are sweet and lovely moments between the leads, but the plot doesn't stray away from the mystery, revenge, etc.

In AoS, they help each other gain their powers back. In TFJ, they are helping each other with their illness and schemes.

The stories are different.
But the MCs share a house.
They are rivals.
Lots of bickering
They can't stand each other lol
Quite funny too

Guyssss, I have only seen the released episodes of Love Has Fireworks (4 eps), but so far it is giving major Love is Sweet vibes.

- Office setting
- In LIS, they're neighbours, and in LHF, they're housemates
-Interesting supporting characters
-Great acting
-They can't stand each other
-THE BICKERING AND CHAOS

Also, I find both the ML's personality kinda similar. They are silly, funny, and lovely.

I watched Love is Sweet years back so I don't remember much but the released eps of LHF reminded me of Yuan Shuai & Jiang Jun.
---- Will update this after completing LHF ---
