Both dramas have intelligent, business savvy, and successful female leads rejected by the male lead during their school days. They meet again as adults, and both male leads excel in the science field and grow to see their respective female leads in a new light. There is also a similar plot line where the female and male lead are anonymous online friends at one point in the past.

-Same producer, composer, overlapping staff

-Similar themes of supernatural oni-like warriors with powers based on Japanese folklore fighting ancient, ghostly yokai

-The main focus of the story isn't the superpowered heroes but a normal human who is dealing with a crossroads in their life and befriends the superheroes

Subtle biblical references, relationships between brothers, extreme situations that make characters go through emotional crisis and very tearful melodrama, all the ingredients are found in both dramas.

A mysterious girl transfer school to expose the lies and misdeeds of the students.
If you like GFN, KNM is recommended.

Both dramas tell the story of King Sukjong and his wives from totally different sides/perspectives. Royal Consort Choi's side is told on Dong Yi while Royal Consort Jang's side is told in Jang Ok Jung.

First I want to recommend you to watch; Love Like the Galaxy; Part 1, otherwise part 2 doesn't make sense.
* Both FL's have to struggle through their childhood with a bullying family
* Both FL's are quiet but clever and finally smart-out this family
* Both FL's are clueless about what being in-love really means
* Both FL's almost marry the 2th lead
* Both FL's stand by their partner no matter what
* Both ML's are cunning and make it to the top through merits of war

TSoML is more cunning and scholarly driven and more focused on the women within the society
LLtG is more scheming and revenge driven about something that happened long ago and still has a great impact on society

They are both fantastic productions and well acted

The plot's different but you'll get the similarity if you've finished watching Upcoming Summer. They both leave you with a nostalgic and bittersweet feeling. First love

They are both thriller, suspense and a noir drama. The male lead was also accused of committing a crime that he didn't do. He was similarly fighting against a powerful villain who wants him eradicated. The male lead is to boot an orphan like the male lead in Big Mouth.

Both disaster movies with many different characters. Although the plots are different, there are many similarities such as:
both the main characters have daughters
The are minor inconveniences at the beginning
The governmental ppl trying to save the victims

So they are both disaster movies, with main characters who have children.
Both about a virus spreading to innocent people and will probably bring tears to your eyes

These are similar in a way that they are both dating shows that test the premise of falling in love with only the inner selves of the other person. This is done with the participants interacting first with each other without seeing the other person's face.

In Love is Blind Japan, they can still hear the voice of the person they are dating but in Love In, they have avatars (which are hired actors) who are going to interact with each other. The duration of their getting to know each other part also differ. Since Love is Blind has the end goal of engagement, that show has longer time. Meanwhile in Love in, they only had 3 days.

Both are entertaining , but I am really liking the concept of Love In so much. You have avatars and actual people who instructs them what to do. There are times that the avatars looks enthusiastic but the real person is unattached and vice versa. I just watched the first episode and now I just want the next.

Both dramas are a mix of crime/mystery and legal genres involving a serial killer. Determining who is guilty and innocent is difficult at the beginning, with many twists in the plot. Both dramas have a similar tone/feel.

Both are BL dramas that include romantic relationship between a professional debt collector and someone who owns a great deal of a debt.
