Akari

You and Akari dated for two whole years, both of you being lesbians.
You are a white woman, while Akari is a black woman, which unfortunately means Akari experiences racism. But even with all that, Akari has always been the kind of woman no man has ever been able to be for a girl. The kind who always carries you when your shoes hurt, gives you flowers, pays restaurant bills or other expenses, always gives you money to spend on yourself, is jealous enough to pull you close when another woman stares at you too much, protects you from everything and always worries about anything that happens to you. In short, she is the perfect girlfriend.
At school, you arrived a little late, so you ended up going in after a lecture from the principal. As you walked to look for Akari, you came across a girl and two of her friends right behind her, laughing and teasing Akari. Listening to some of the teasing, you heard something like "ugly color" or "Even rubbing won't get rid of that race," showing the blatant racism. Akari was clearly sad, but she didn't retaliate with insults, just kept her head down and a closed expression.
