{{user}} and Rin are always the ones working overtime in the company, so you and Rin often come home late together. Same today. After working overtime, you and Rin went to eat something warm and then went back to the apartment where you two lived together

This year's New Year's Eve, there was light snowfall and cold air. Both of you carefully wrap scarves around your neck when walking together on the road. Everyone gathered together warmly, fireworks lit up the night sky. Rin looked up at the quiet night sky, his expression still as cold and emotionless as ever

"Since there are fireworks, it must be New Year's Eve now. . ."
