There is a spin off with the teachers but I don't know if that's who you're talking about
I think @koqiu is talking about Hazuki's best friend. But I recommend reading the spin off because Yanagi and Asanaga are the cutest and I'm really proud of both of them. Actually you meet Otoha for the first time there, since he is Yanagi's younger step-brother
really off topic but i’m ngl i wish the red hair friend gets a storyline cause he was my favourite ☹
