Sweet 18 (2004)

They have the same lead actress for one; and a lot of the music, filming & characters tend to remind me of this drama - they are both, sweet, romantic & fun :P

GB reminds of Sweet18.

Similarities:
Older ML/ younger FL
Educated ML/ FL only has basic education
Hate to love relationship
In both series FL mainly dreams of being a good housewife
In both dramas the FL has the Father/Mother in law’s support

I enjoyed Sweet 18 more than GB. GB has some really good scenes but it also has annoying characters.

Following a failed confession to her first love, female high school student Mikoto Ochiai contemplates jumping off the roof of the school building. However, her thoughts are interrupted by the arrival of Jin Haiba, the physics teacher known for being a slacker and the butt of students' jokes. Calmly, he lights a cigarette and asks for an explanation of the events that led her to this precipice. Rather than dissuade her from killing herself, he makes a request—will she enter into a romance with him before she dies? Together, the two gradually ponder why they should keep living and why they should not love each other in earnest.

Both dramas deal with a couple getting married because of an arrangement and because the girl is head over heels for the guy. Though Wedding is more mature than than Sweet 18.

Even though these are two different stories, they both have an age gap between the main couple. In who are the girl is 20 and the guy is 31, and in Sweet 18 the girl is 18 while the guy is 28.

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!

In sweet 18 the ML is prosecutor, while in P to JK ML is a police officer. Both dramas have an older guy falling for a younger girl, both are cute stories and both have cute couples. I really love both dramas, I think if you like Sweet 18 you will probably like P to JK as well ^_^

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

both are romantic comedies that show a funny and sweet clash between traditional country clan life and city life, with a leaning toward preserving tradition.

main couples in both dramas start their love story anew after marriage and the female lead in each is an uneducated simple woman fighting against a sophisticated rival and her own insecurities to win the heart of the gorgeous husband.

Both stories about a young girl getting married, except in this one, the girl is supposed to marry the main lead's brother. The drama that made me fall for Yoon Kye-Sang. It's old but still one of my favorites.

Both dramas have teen marriage genre and the FL's of both dramas love ML first and wants to marry him. Both the dramas are light-hearted comedies.

Ayaka, who works at the bridal department at a hotel, has a beauty that everyone recognizes, yet her personality is the worst. Everyone calls her a "wicked woman" after the way she wraps numerous men around her finger. The one who sets his eyes on her is the hotel's new executive Togo, who is the son of a very powerful person of the town. What are the orders that this King-like man requests of her!?

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.

Forced marriages, husband and wife eventually fall in love. This one has one difference that both have good trust in one another as in drama does not lie much in dragging with misunderstandings
