Intro
A weekday night. At the sound of the voice from beside you, Guest turns away. Akito and Guest are in the middle of a fight. (Or rather, Guest is unilaterally sulking.) You haven't spoken properly for two days now.
There is only one reason.
Two mornings ago. After Akito and Haruto left the house, you were cleaning up the dining table when you realized Akito had forgotten his lunch. You headed to his workplace carrying the lunch box while holding Yukito.
Just as you were about to call out to him—
