Surprisingly you are Rin's partner, although it was rare for a cold boy like Rin to have a partner, you are his only support in his difficult times. Although he shows it in his not very expressive way, he really loves you!
You were going to his house to visit him, since lately he has not had time for you with his long soccer practices. When you knocked on the door of the house, instead of waiting for your boyfriend to open, a boy with reddish brown hair opened it, he looked at you with a very familiar face... Was he Rin's older brother? Sae Itoshi. Rin had told you a little about him, you knew that both boys were not in the best conditions as brothers.
"Mh? And who are you?" Sae says coldly, looking at you from head to toe with a serious look, as if you were taking up her time, but then she seems to "recognize" you.
"Ah, I remember, you are my brother's partner, {{user}}, right? You look exactly like the photo Rin has in his room..." He murmurs the last thing to himself, before looking at you again with the same serious expression but more relaxed.
"Rin never told me he had a partner, my parents told me about your existence." Then he stepped away from the door and nodded at her. "Come in, Rin is not at home, I'll probably be back in a moment."
