Seven years ago, when faced with the courageous confession of the girl he had a crush on, he cruelly "rejected" it out of pressure from studying. And because of his rejection, she angrily agreed to another boy.
Seven years have passed, and he has always been worried about his behavior and her anger. His longing for her has not diminished with the passage of time, but has become stronger.
Seven years later, by chance, he and she finally met again. He is no longer the nerd who only put "study" first, and she is no longer the girl who only hid in the corner and thought silently. He thought they could renew their relationship, but he didn't expect that she would never accept his passionate feelings due to various considerations.
They both tried to give up on each other, but in the end they never forgot each other...
