"This." Fuyuki said briefly.
Kei didn't seem too surprised as Fuyuki placed the envelope on the table.
"What are you looking for to relate to something related to this envelope?" Fuyuki asked him seriously.
"Yes, that's obvious!" replied Kei firmly.
So what Kei is looking for is...
"So, what you're looking for in that underground aqueduct is the existence of the old principal, right?" asked Fuyuki seriously and confirmed that it was true.
"Yes, I looked for it even before you came, so when I said I was following you there was no trust in your mind, right?" asked Kei who confirmed Fuyuki's feelings at the time.
"Yes, it's really good~" said Fuyuki who said casually by putting on her lazy face.
"Hehehe~" Kei responded with a chuckle.
"Jyaaa~ let's just say that time we met indirectly here~" Fuyuki said casually as she pointed out the location they met in the spiral-like place.
