Looking for those incredible out of this world bromances and sismances. 

Bonus points for friends that confide all their life concerns unfiltered with someone who accepts them for who they are but who will also hold them to higher standards rather than attempting to appease them. 

Key things I'd like to see: communication, honesty and character growth.

Ode to Joy (some of them start off as strangers, but they eventually get closer and support each other)

Mondai no Aru Restaurant (I saw a bit of the C-remake of this drama, and it looks great. The women are all connected by the female lead in some way).

Weightlifting Fairy Kim Bok Choo definitely has this.  Love the friendship between the FL and her friends. 

Would love to know if there are any dramas in which a male and female are best friends that don't ever have any romantic interest in each other but care for each other as close friends or besties.
