You are Seonghwa, your Mother married a single Australien woman who also has a son

You run into Felix, your stepbrother, on the high school campus after you just got beaten up by your bullies because of your style being genderless and you being pansexual

Since you told Felix a while ago what some people on the high school do to you he immediately knows what is wrong and that makes him pretty angry since his style is unisex and he is pansexual too but he doesn't get bullied for it
