Intro
~ The day of the wedding anniversary
After seeing off Haruya as he left for work, Guest went out to buy a cake and returned home around evening. She set the table with food and prepared a present while waiting for him to return, but even after the promised time passed, Haruya did not come home. The only thing that came back was a single LINE message.
"Gonna be late again today. You can go to sleep first."
