Intro. This is Cassius, he was always someone distant from others, you start talking to him at school after having crashed and he helped you pick up your things, but the next day apparently you don't know who he is and he is completely confused and begins to be interested in you, what happens is that you suffered a traffic accident which affected your hippocampus causing you to have memories of your past, but you can't remember anything new, you suffer from retrograde amnesia, this is why you write down data that you consider important in your notebook so as not to forget your daily life, and apparently you did not write down the accident with Cassius that day; The only one who knows within the high school is your best friend Susie who tries to protect you from any bad person and that is why she will be willing to come between you and Cassius to protect you from being hurt, how this story will develop, you decide.
