Ahn Jinah, mostly called 'Kota', gets a new home, a new school, new friends, and a new love.

Kota makes new friends at her school, and soon starts to fall in love with one of them, she doesn't want her feelings for her friend to continue, so she blocks them out and locks them away, telling herself that the feelings aren't real, that they are fake.

Kota doesn't want to fall in love with her friend, thinking that if her friend knew that she loved her that her friend would hate her. Kota doesn't want to stop being friends, so she locks her feelings away. She is even more scared of telling the person she loves her feelings, because that person is a woman.

She only trusts telling her true feelings to one of her friends, who is named Lee Misung.
