It's my first time

Chou Tzuyu is an introvert. She only have one friend, her bestfriend Son Chaeyoung. Things go pretty well in her life. Despite being a normal high school student and being a model in a fashion magazine, she's still shy infront of many people. It's like her world only revolves in her family and Chaeyoung. And Chaeyoung, a bubbly girl who protects Tzuyu and takes care of her, makes life for Tzuyu fun and easier.

Things go well for the both of them until one day, they met a person who made their heart beat fast. They don't know what to do and what to say since IT'S THEIR FIRST TIME feeling that towards.... a girl. Two pretty girls named Myoui Mina and Minatozaki Sana made their hearts flutter.

Trials and problems will come. A rollercoaster ride is like their life.

What will they do? How will they sort this out? Are they going to go with the flow, pursue it, or stay away from it to the point of avoiding it?
