Recommendations

In both dramas, the leads work as news anchor. We see them in their work place in most of the drama and can have a glimpse of how things work in this field.

One drama is a comedy/romance while the other is more of a drama with some comedy and romance.

When I watched Go Ho's Starry Night, I thought there are some similarities with Her Lovely Heels. But I think if you're into stories that involve a love triangle between a woman, her new guy and her ex-boyfriend I think you should watch Discovery of Romance and Go Ho's Starry Night.

I am not finished with Sassy Go Go, but the stories are about the main character(s) facing the harsh realities of life. Both dramas show things that other dramas like to sugarcoat (Ex: Lgtb, self-harm, economy problems, kidnapping, etc...). There are moments where you want to cry and there are moments that you can not help but to laugh; both dramas give you those emotions.

I'm surprised no one made this recommendation yet. In one sentence, Prince of Lan Ling is the same story as Princess of Lanling King, both on Lan Ling Wang.

Two movies that involve children without parents, abused and used. In both movies there is a person that tries to protect them.

The female lead time-travels to the past and falls in love with the male lead.

And any other season of Aibou!! The New Office created, despite its name in both series seems merely like a demotion office than anything else. Indeed as no real assignments are given to the police inspectors there. Nevertheless, they still get involved in cases they shouldn't be working on, thus often solving incidents without any recognition. And lastly, despite the premise of both dramas it is much more comedic than it appears to be.

Similarities because of the "New Service" (or Nandemo Suru would suit better) created within the department of Police, when in fact it's just a plain office where nobody wishes to be. It only exists to deal with small and/or odd jobs. But there's one man there that only listen to his instincts and has quite some flair when it comes to solve crimes.

These two both reminded me of Resident Evil. They're pretty similar and though Train to Busan is pretty popular, I suggest you to watch Live Shock too.

Both involve adventures with a team of people explore old places which have traps and secrets hidden. Both have mystery, suspense and action elements.

Similarly hollow feeling to the stories. Both are captivating and easy to watch with very nice cinematography. Romance isn't super prominent, and both carry a supernatural theme, with Goblin leaning more on the high-fantasy historical side and YWCFTS more modern and not as "epic".
While Goblin's conflict stays more on the supernatural side of things, YWCFTS' conflict is a murderer. Has a more "earthly" feel than Goblin, but similar overall.

Both great and sometimes sad love stories that are extremely touching.

They are both supernatural. You know... Ghosts... Gods... Grim Reapers... and so on.
In both dramas we have 2 couples. AATM has love triangle but it's not very strong but Goblin has none.
AATM has mystery and suspense but Goblin doesn't.
Goblin is way more hilarious than AATM.
Acting in both is superb.
They both have bromance but the bromance in Goblin is more sweet. hilarious and strong.

these 2 dramas have some similarities. the villain is a spoiled chaebol's son who's the president of a big company. they have issues with anger management and no matter how much evidence the cops have against them, they come clear due to their connections.
