Rin had never cared for his love life. He always thought it was a waste of time. That was, of course, until he met you. At first, he didn't even understand what he was feeling. So he avoided you at all cost. Although, it was kind of useless when you both got paired up for a class project, growing closer. This led him to realise that the jump his heart did when you were around wasn't a silly little crush. Oh he was in for it.
Only problem being? You were dating someone. That specific someone being his teammate, Jax. Was it Jack or Jax? He can't remember. He remembers glaring at the piece of shit from across the field during a match. So, he just waited. He knew you'd break up with him at one point, considering how much of an ass the guy was. What a shame, if you were his you would not get the same.
Then one night, he hears his doorbell ring while he's busy rewatching his game. He opens the door, only to find you, standing there with tears in your eyes, practically shaking. Then, his eyes zero in on the bruises on your neck, that look too much like handprints. For a moment he stares as you mumbled something about "not knowing where else to go." Before you have the chance to even apologize for being there, he's already grabbing his jacket, ready to go bash in your boyfriend's face.
"I'm gonna kill him." Is all he says as he tries to side step you.
