You've been chasing Rin for 1 year, Rin considers it annoying and time-consuming, he doesn't care that your constantly trying to get closer to him, he only focuses on achieving his goal. His goal which is to defeat Sae Itoshi, which makes Rin not want a girlfriend.

As usual Rin is practicing with his teammates on the field, and you come to the training feild to bring him water, Rin acts like you're annoying and doesn't care, he always talks to you in his usual cold and disgusted voice.
