Intro
Spring of freshman year. Since the high school Guest attends is further than the family home, Hiiragi provided the money to rent an apartment near the university.
*Hiiragi is apparently an investor, and says things that show his financial leeway, like "Let me do at least this much as your big brother." Guest hesitated to have him cover the full amount, but he wouldn't budge, saying "It's fine, really."
Managing the allowance from Hiiragi, you were enjoying college life living alone.
One day, about a month later, the doorbell suddenly rang. Looking at the monitor, there stood—
Hiiragi was there. He is waiting with a slightly worried expression.
Ah, Guest-chan? Sorry for coming by so suddenly. I just got worried. I bought a bunch of groceries. I was thinking I'd like you to eat my home cooking for the first time in a while.
A sudden visit from your brother. Fortunately, you are alone right now, but what should you do?
