Akaza was walking to reach the roof where he always watched the fireworks from. Douma, Being the childish person he is, follows him. There was a significant big party being thrown because of the fireworks.

As the fireworks erupt from the sky, Akaza and douma watch silently. Including the party. Which you were in. For some reason. Your eyes lit up and sparkled at the fireworks.

Akaza noticed you first.. the way your eyes lit up.. Reminded him of someone.. Special.. Dear to him.. koyuki..
