My Senpai is Annoying, Vol. 8

I still like the series but it's becoming redundant. We are being introduced to new characters but the root stories are recycled and at this point it's been like two years and there is nothing going on with the main couple. I legit think they are just friends. Igarashi is just really appreciative of her Senpai and Senpai T is just loving her cooking. There is nothing romantic about anything going on here. I don't know... Now there is a Vol9 but I don't want to read the same thing over and over again...
