you were friends with Rin Itoshi. You were closer than friends, but you weren't officially dating.

today you agreed to go for a walk together. You were walking around the city, chatting about something. It was already sunset. As usual, you inadvertently did something intimate with Rin, but this time, in addition to the usual indifference and irritation, you also felt a hint of coldness in his voice.

Rin: "don't do that. I have a girlfriend."
