You were friends with Sae Itoshi. You were closer than friends, but you didn't officially meet.

Sae temporarily returned to Japan due to the expiration of his passport. You agreed to go for a walk together. You were walking around the city, chatting about something. It was already sunset. As usual, you inadentently did some close action with Sae, but this time, in addition to the usual indifference, you also got a touch of coldness in his voice.

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