My Girl (2005)

a love triangle between two friends and a girl.

Both dramas involve cohabitation, 2 Male suitors, & a hotel setting. The vibe for them also feels similar.

Both have a very similar plot in which the ML hires FL to be the long lost granddaughter of some super rich guy. My Girl is a Korean classic, while Taking Love as a Contract is a low budget minidrama that almost seems like a remake due to the similar premise. The endings, however, are different.

Both are classics must watch to me.
The leads meet casually and become "partners in crime". Both MLs are in love with someone else at the beggining but, when they eventually fall in love with the FL, they can't easily get a happy ending because in My girl they have to fake they're cousins and in My princess they're apparently enemies.
Very interesting plots, with many moments that make you laugh and others that make you cry!

Rainbow Sweetheart is the Taiwanese version of "My girl"

19-year-old beautiful Shiratori Reiko is a self-professed ultimate princess. Despite her haughty attitude, she is actually a very late bloomer and knows nothing of the real world. Reiko has had feelings for Akimoto Tetsuya since childhood, but her enormous pride always gets in the way, and she cannot tell him in all honesty that she is in love with him.

Tetsuya soon becomes a university student, and Reiko follows him to Tokyo. But he is constantly at the mercy of her overly unique sensibilities. Then Tetsuya’s ex-girlfriend, a cute high school girl, the wealthy Yoshimoto Ryunosuke, who has fallen in love at first sight with Reiko and Reiko’s rival, Kakitsubata Ayame, appears before the two of them.

If you liked My Girl, you might like Just You because they're about the main characters living together and falling in love. The male leads are the 'boss' and the females are the 'employee' in both dramas. (I personally liked Just You better)

These are two of the funniest dramas ever for me. Plus, they are both written by the Hong sisters.

Both dramas has very similar comedy and both are dramas by the well known Hong Sisters.

If you liked my girl for lee da hee you would definily like marriage no dating the same concept of a man bring someone home to Fake their relationship in my girl as cousin here as girlfriend and the same beautiful romance with completely funny scenes also Han groo has same attractive spirit lee da hee had at my girl :)

The plot is really similar, hiring a girl to pretend to be sibling.

In my girl also the two guys are friends.
One of the guy is a playboy.

An person is hired to play the part of a long lost family member to appease a dying family member forms the premise of both stories.
