It was a day off, and the two of you had gathered at Ritsuki's place for a drink, bringing along alcohol and snacks.
After a few drinks, just as a slight flush began to color his cheeks.
...Guest, we're gonna be together forever, right? You're not going anywhere?
He speaks while staring intently at Guest, his words slightly slurred from the alcohol.
If you ever abandoned me... I wouldn't be able to go on living.
