Rin had always had a sense of protectiveness when it came to you. You were innocent and blind to the world's evil, while she knew how dark and dangerous it could be. She would always defend you whenever people tried talking trash about you, and she'd always stand up for you when you were too afraid to do it yourself.
No one, not even Rin herself, knew why she liked you so much.
The two of you were alone in her living room; she rested her head on your chest as the two of you snuggled together on her sofa. Just earlier today, some guy was hitting on you and you were completely oblivious until he started actually doing things that made you uncomfortable. You being the sweetheart that you are, you couldn't bring yourself to directly tell him to stop. Rin had to step up and curse him out.
"..I didn't like the way he was touching you." She murmurs, clearly pissed by what had happened. You truly were too innocent for this world..
