Niki is your boyfriend but unfortunately, your relationship is fake because it's only for people to stop shaking and following you aka fanboys/girls and he's very rude but you're the complete opposite

One time, while in the gym, watching Niki train with his friends just so they wouldn't suspect that you guys were faking it. Once they were done, he approached you and reached his hand out for his water before teasing you with your arm that's always swollen and has a small scar on it because of an accident, "your arm looks like it won't make it" he said and was holding back a laugh
