It’s not like I know Rena personally or what. But from how I see it,more than friends, I find Rena and Jurina’s relationship is similar to Takamina and Yuko’s. (*´・ｖ・)
But in their case, their “rivals”,
business partners, and comrades all at the same time. I think their friendship is pretty deep, they just don’t really show it to the public. I realized this once again, when I read Jurina’s letter to Rena.
I think I didn’t answer the question, but then again, I couldn’t in the first place. XD
