"Why did Grandfather..."
"He expressed his gratitude for me and invited me over for dinner at his home tomorrow night."
"Oh..."
"I was wondering whether or not to bring them some presents. What do your grandfather and grandmother like?"
"I... I don't really know," Hoshi replied.
"I see." Seiji rubbed his chin in contemplation. "Although I could still call the confectionery store owner and ask... forget it, I'll just bring over some desserts."
"I think that it's not necessary for Senpai to bring anything."
"That's fine as well, but I still think it's better to bring something rather than arrive empty-handed." Seiji sighed. "I never expected your grandfather to express his gratitude to me in such a formal fashion."
"Yeah... I'm surprised as well, but it does seem like something my grandfather would do," Hoshi chuckled. "Senpai, just accept my grandfather's gratitude."
