Haha. Tora (I guess we can call her that?) is pretty weird. Following Yamashita (wut? we still haven't found out what the main character's first name is?) around without doing anything. I agree that this chapter was cute, but where it's going is still a mystery.
Dunno what to make of the sempai character just yet. Well, going by the volume cover from the first chapter, seems like she'll just be one of those fanservice-providing voyeurs/perverts, lol. I'll be looking forward to seeing how Yamashita and Tora's relationship develops.
