Age isn't everything, It shouldn't be an excuse. People can have a good mind and maturity at a young age which some older people might lack. He is not devoted he is obsessed, and in the wrong way. He might not have bad intentions, but he is still in the way, he needs to grow up, and think about things with a clear mind. Hence stop with the overdosing on drugs thing. ╮(●へ●)╭ Sorry to have to say.
I just feel bad for Rin he's young and doesn't know much...he's devoted and somewhat innocent...he should find happiness with someone he'll fall in love with.
