Itazura na Kiss: Love in Tokyo (2013)

Both dramas have a mean cold-hearted lead male character in the beginning. Also, there seems to be a concept similarity in two of the main leads being in the wrong relationships in both "She Was Pretty" and "Itazura na Kiss".

Main girl in both are quite exaggerated, although I would say Itazura na kiss is more extreme, but both also have similar plots I guess, same kind of ending I would say.

It's the first film version of the InK and another one to add to the 'stable'. All the characters are the same and the story follows the original manga/anime; much as this drama did.

If you like cold hearted guys then this ones for you its just that in Mkschievous Kiss the girl has a crush on the ML but in WGBP the dont really like each other at the beginninb

It's similar in the way that it's quirky, maybe not as quirky as Kotoko though.
There's also some comedy in KonoKoi, and a much more mature cast.

The romance factor is unrequited for the most part, similar to Itazura na Kiss.
There might be more heartache in KonoKoi because it only has ten episodes, while ItaKiss has two seasons.

The age gap between both leads are at least over ten years.
Naoki (Yuki Furukawa) and Kotoko (Honoka Yahagi) are ten years apart in age, while Takumi (Tomoya Nakamura) and Kiki (Nana Mori) are fourteen years apart in age.

I personally think that they both are really funny. And Hana Yori Dango is super sweet and adorable, just like Mischievious Kiss.

Saimori Miyo was the unfortunate child of a loveless, arranged marriage. After her mother died, her father brought in his lover and her own daughter, Kaya. From then on, Miyo's life was reduced to that of a mere servant. Even worse, while Kaya inherited the family's psychic abilities, Miyo had none—she was truly the daughter with no merit. After years of being treated like dirt, Miyo has learned to keep her head down, hide her pain, and obey every order. So, it comes as no surprise that she is arranged to be married to Kudo Kiyoka, a military captain rumored to be so cruel that he has driven away every one of his potential wives so far. From a painful upbringing to a painful marriage, that's the future that awaits Miyo—or so she thinks. Contrary to her expectations, her new husband is actually kind-hearted. What really awaits Miyo is a blissful, everlasting marriage full of happiness!

At a high school entrance ceremony, high school student Kotoko Aihara, who isn't that smart, notices pretty boy Naoki Irie. She falls in love with him immediately.

Even though their marriage starts as a sham, will the day come when this couple can become something more?

They both have a cool, pokerfaced, 'attractive' male lead. And a girl who is a bit naive. both have happy endings with a lot of love. the difference is that itzaura na kiss is about school life, whereas cruel romance is between two people that are living in a big city and are a bit older. Both are cute and have funny and sad scenes.

Both dramas have a "perfect" ML and "mediocre" FL falling in love. Also the ML in both dramas is helping the FL with her studies and they are cohabiting.
In P&C they are both adults and start with a student-professor relationship while in InK they are in high school to university. There is also no contract marriage in Itazura.
I enjoyed both.

Both are about high school love and both girls are head over heals for the guys.

Both of these Dramas depict a a clumsy girl chasing a rich, attractive and smart man. To accomplish her dreams of being with him, the female lead receives help from the male lead's family. Also, they show a large part of the life style of a married couple.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide
