Siena is in love since college. That was her motivation to go to the university where she is invincible to everybody. To see him sitting in front of her in two of her class is her addiction. She memorizes him in her heart until he graduated. Being at the top of her class, her previous professors do not understand why she wanted to be an assistant instead of aiming for a higher position. That was all she wanted, to be near with A Ramirez.

B is the other half of the Ramirez twins. He is used to being called A most of the time. He doesnt mind at all until Siena came. The game he and his twin played is not as fun as before anymore. Being called by his name is refreshing to him. Only their family can tell him and A apart and knowing Siena can see him made her stand out.

But B is not prepared for the rejection in front of him. He is craving to have a whole when all of his life, he always gets a half. And this time, he is determined not to share her love with his twin brother.
