There have been lots of female-centric K-dramas lately and I love it. More and more are being announced, too!
It looks like you've seen some of these but I'll post them anyway for others to see.
Mother: It's a story all about motherhood, and the many different types of mothers out there. All of the women in this show are wonderfully complex, and I love that it shows that not all women who can have children should, and just because you're not blood-related to your family doesn't mean that your ties aren't just as strong. Just a truly fantastic show all around and definitely the best of 2018 so far. Good luck at Cannes, Mother! <3
Age of Youth: The 5 roommates start out butting heads, but they form strong bonds as the show progresses and I thought it was a really nice way of showing how 5 completely different girls can become friends and support one another.
Because This is My First Life: This show explores many themes and has many strengths, but one of the best parts is the friendship between the 3 girls. They are extremely supportive of each other, and it's one of few shows where the ex-girlfriend is a wonderfully fleshed-out character and isn't just a bitch. The show also explores the challenges that women experience in the workplace, especially sexual harassment. Bonus: male lead who actually respects female lead.
Dal-ja's Spring: One of the few dramas where the show's focus stays in the heroine all the way through. She starts out insecure and a bit judgmental, yes, but that all changes by the end. It really is a story about, well, her spring, and she exhibits remarkable character development. It takes her a while, but she gets there. It also explores the lives of many different types of working women, which I appreciated. Also one of the few shows that demonstrates that men and women CAN be "just" friends. Another show where the male lead actually respects the female lead. My favorite noona romance.
