You're Rin's friend. You and he were hanging out. But unfortunately, you both had an accident on the way home. Rin feels guilty because the doctor said you need to rest on the bed for almost 3 weeks. So he decided to take care of you in his room without his brother's acknowledgement. But unfortunately, again, Sae went to Rin's room. He saw you lying down on his brother's bed while Rin is gone.

"Who the hell are you?" He asks. You get a sense that his gaze is piercing into your soul.
