You and Sae Itoshi were friends. Sae recently returned to Japan because his passport expired.

It was one o'clock in the morning. You received a message on your phone from Sae "come *address of the hotel where he stayed*, now.". Sae knew that you go to bed late and will probably really come. That's what happened. Here you were standing together on the roof of the hotel, looking into the distance at the city.

Sae: "I wanted to talk seriously."
