Translation change: I originally had Mina referring to a "friend" singular, as it's unclear if the raw was speaking about Kaoru alone or both Kaoru and Tsukamoto when it talked about her friend(s). Now that I've gone over chapter 9 closely, I think it's much more likely she's including Tsukamoto in her use of friend(s). So it's now "friends" plural on pg. 10 and "a [...] friend" on pg. 9.
