Both Hitsudan Hostess and I Just Wanna Hug You (aka Dakishimetai - Shinjitsu no Monogatari) are centered around a female main character with a disability, in both cases played by Kitagawa Keiko

Both Hitsudan Hostess and Kimi no Te ga Sasayaite Iru are centered around a deaf female as the main character

in a nutshell: Good looking men with feline characteristics

how are they different?
-drama vs. webtoon,
-length which translates to character development
-episodic as opposed to MLP with one unifying plot and fuller story
-appearance of cat characteristics...in MLP they only appear when the ML is emotionally agitated, they dissipate when he is happy

both dramas are about shopping addict people
both main leads are from rich family
their lives changes ovenight and they must make money on their own

This drama is something which I was searching for a long time, I still remember watching how to buy a friend and truly loved the drama...

The actors , direction, story ,cinematography , ost ,and the atmosphere...
Love it.. just like how to buy a friend

Both mysterious and thrilling.
Both have a way of changing the future, where in 'Signal' is through communicating in to the past through a walky talky, and '365: repeat the year' is by going back exactly one year.
There are also detectives as leads in both shows.

Although it's not a school drama, the leads in these dramas are super similiar. They both have to do illegal things to earn money, they have no parents in their life/ have a parent who treats them horribly, they have to keep secrets from the people around them, and they are both really smart. Both of these dramas have dark undertones and smart female characters

Just based on the synopsis: both begin in the modern world where a female writer is writing a historical love triangle for work. In both, neither writer intends for the female in their story to live long, but as the writer gets deeper and more connected to the story, she has to find ways to stay alive in the world she has created.

(Rule the World is a great option while waiting for the release of Romance of Tiger Rose)

Both based on the same novel, both entertained the possibility of historical Korean painter Shin Yun Bok as a woman pretending to be a man because her paintings mainly depict women. The two stories interpret the story of Shin Yun Bok being a real woman quite differently, but the similarity in both shows is that the historical character Kim Hong Do(who was a fellow painter of Shin Yun Bok in Joseon era) is her teacher and is also one of the 2 characters who fell in love with her. Both shows depict Shin Yun Bok's life as a woman loved by 2 very different people while living her life as a painter.

Both are Joseon period dramas about a woman's struggles to become a great artist. I really love both dramas because both plots explain the characters very well through the use of their art forms. Both dramas also feature a beautiful and talented gisaeng played by two great actresses (though the gisaeng in Painter of the Wind is NOT the lead female). A scene I find quite similar in both dramas is both feature a scene wherein the gisaeng is playing the gayageum instrument while her lover (in Painter of the Wind, this lover is the female lead) is painting as the lover listens to her music.

Both depicts a story of a woman who was born a noble yet circumstances in her life led her to be linked with a much older man (an official who owns her as a gisaeng in Hwang Jin Yi, a professional painter who became her trainer in Portrait of a Beauty). Both women are very talented, either as a poet or as a painter. Both older men are very much attracted to the young woman linked to them. Despite the older men's attraction, both young women fell in love with a man closer to their age who basically has a low position in Joseon's class based hierarchy. The love triangle in both these shows are then lead to chaos on the three main characters' lives until the ending.

This is related as it involves a taboo relationship with a student and her teacher. Although it is not as cheerful as Hello Mr.Right, it is still an amazing series to watch. It will literally make you cry!

Before actor Ryu Seung Ryong became popular with Miracle Cell No. 7 and Kingdom Netflix series. I have seen his great performances as a villain in these two shows that has a gisaeng as an important character.
(Bonus: As a result, while most people are surprised that the kind but imprisoned father in Miracle Cell 7 is the same guy in Kingdom, I am actually surprised that he could pull off a kind character in Miracle Cell 7 after seeing his villainy in these 2 shows).
These are the similarities of the 2 shows:
1. Both shows have a gisaeng as an important character (though the gisaeng in Painter of the Wind is not the main character)
2. Both gisaengs are beautiful and is the most desirable gisaeng in the land
3. The main villain in both shows is a much older official played very well by actor Ryu Seung Ryong, who lusts after the gisaeng. He was able to own the gisaeng as a property.
4. Because the gisaeng loves another "man", Ryu Seung Ryong's character wants to get rid of that "man".
5. The "man" the gisaeng loves in both shows are very talented in their own field (the one in Painter of the Wind is good at painting, the one is Hwang Jin Yi is good in martial arts)

Done around the same time period, 2006-2007, both shows are different retellings of Hwang Jin Yi. If you want to focus more on Hwang Jin Yi's talent as a gisaeng, as well as colorful costumes, then you might want to watch the T.V. series. If you want to watch a depiction much closer to her real life (according to some people), you can watch the movie. It's good if you watch both though, as both shows depict two different views of the modern world on the historical Hwang Ji Ni and the impact of her charms and talents to the modern world.

Similarities:
=> Both are stories of a romance between a woman who is supposed to be a crown princess and a man destined to be king
=> A 12 year old Kim So Hyun gives a very excellent performance as the young version of the woman who usurps the crown princess position. (In a way she's actually the one who played the usurpers, not the adult actresses, because the takeover of the crown princess position from the real crown princess is done by her character in her teen years).
=> We see the male lead (or rather the young version of the male lead in Moon Sun) attracted to a girl with a butterfly in the first episode.
=> The male lead (him or his doppelganger in Rooftop Prince) has a close relative who can be a threat for high position he has (the king position in Moon Sun, being the heir of the company in Rooftop Prince)
=> Lee Tae Ri/Lee Min Ho actor born 1993 gave excellent performances in both dramas. Both his characters in a drama is a very smart young man who helps one of the main characters.
