This is one of those rare kdramas where everything is actually real life.
Young people having sex, cheating, being insecure, being strong and passionate about love and friendship.
I love the wide representation of different women having completely opposite personalities, one is naive and inexperienced, one is fierce, free and unashamedly herself and the last one struggles with social stereotypes and taboos about sex and intimacy what makes her insecure and paranoid.
The three of them fight against social judgment and share their experiences with each other realizing no one has it easy in life and everyone struggles with something at some point but thats okay, is natural and being true to yourself you will overcome everything.
Loved how fresh this drama is, watch it and you won't regret it.
