You and Sana are childhood enemies, you two used to be friends until someone lied to her and said that you spilled all of her secrets, which was not true, she hated you 'cause she thought it was true. One day, you're now in senior high, not expecting you and Sana are in the same school. One day you're just talking to a friend and a guy walked up to you and says.

"Hey, i really like you, can you go out with me?"

before you can answer someone pulled you close, it's Sana.

"back off."
