She's basically Nagi's childhood best friend who left Japan when they were kids because of her dad's job in China. Years later, she came back specifically for him. Beyond that, she's got a pretty solid following as an online singer—the kind of person who can rack up views doing her thing on the internet.
The thing is, her feelings for Nagi go way back. Like, way back. Fans often note that she's had pictures of him all over her room since they were kids, which tells you everything you need to know about how deep this goes for her.
