Ambos mostram garotas novinhas tentando sobreviver na cidade grande sem dinheiro, sem família e sem lugar para ir. As duas trabalham por um tempo em hostess clubs, e por la ganham uma outra oportunidade maior.
Girl's life é mais voltado para a vida da guria e na amizade que ela conquistou.
Na maior parte de Platonic Sex também é mais sobre a vida da guria, mas acaba virando um romance, ou seja, tem uma emoção a mais.

The drama is about 2 families who go from the picture perfect life to a stage life. Shin Gu runs a photo studio and his kimchee-like common class family is about to become inlaws with Seon Woo Eun-Sook's cheese-like rich class family that runs a sports center, and Kim Eul-Dong plays Shin Gu's wife. Lee Hye-Yeong plays Kim and Shin's unmarried 39 year old daughter. With the clash in class and familyvalues, the drama is the comic events that follow when kimchee and cheese are hashed together

These two dramas are seemingly quite different, but I think they have some themes in common, such as people working through various life issues and the characters trying to help each other through it. There's a theme of family here, in Kahogo no Kahako they are related by blood, but in Last Friends, the friends are like family. Last Friends is quite a bit darker in terms of the issues the characters deal with, but if you liked Kahogo no Kahoko, give Last Friends a try!

Both have awesome swordsman and fight scenes. One is about getting revenge and killing while the other is trying to make amends for past and refuses to kill. Both are awesome movies and have the same feel and character looks.

Both have lead with different personalitie, just that in Meloholic it's the female lead who have different personalities.

This might be far-fecthed similarity but both have characters working in the entertainment industry and I see something similar in Dokko Jin and Do Hyun's characters.

Lee Min Ki in both dramas as the main lead! Cannot unsee though that he plays a kind of reversed role in Because this is my first life as opposed to Dalja's spring; while he is the younger guy dating an older woman in the older drama, he is certainly Dalja in This is my first life, what with being an old spinster type of guy, counting his money and being all scrooge-y.

Both dramas are sweet and about two totally different people developing feelings for each other as they learn to depend on the other while living together, although Kimi wa petto is a bit more extreme with the conditions for tenancy ;)

Falling in love after getting married! Goong has a bit more tears and teenage drama while Because this is my first life is a bit more mature but innocent in a way as well, both are focusing mainly on the development of the main couple's relationship. Also, the main actresses look quite similar.

Both have a time travel theme where the main female character ends up in a time when there is a fierce power struggle for the throne.

Both female lead is a vampire who falls in love with a human male lead. Both show the vampire family members and friends (second male lead) of the female lead and in ICHY, the vampire clan has evolved that they no longer drink blood but gained energy through human contact. However in ICHY, the male lead is a germophobe (dislike human contact) and in OM, the male lead hates vampire.

Same writer and similar scenarios
Lee Jong Suk is also in it.
Instead of having dreams Lee Jong Suk can hear people's inner thoughts.
There is also a strong focus on the justice system.
