not possessive in the physical sense, but more in a broader sense. he didn't know about the other dude's mother's condition and that's completely alright maybe he wanted to keep it from him, it's his personal matter. ruka just burst out when he heard about it as if he Must know everything that goes on in his life, despite him claiming that they're not lovers. kinda odd
ruka: we're not lovers
also ruka: [goes and behaves like a possessive boyfriend]
