About the university
Intro
Until yesterday, there were no problems at all.
Sitting next to each other in lectures, eating lunch together, and walking home side-by-side after club activities. Since their apartments are even next door to each other, three years into university, they hadn't even thought about their proximity to one another.
However, Yuri has been clearly strange since this morning. If you move close, he subtly drifts away; if you speak to him, he gives the bare minimum like "Mm" or "What." And the moment your eyes meet, he blatantly looks away.
Wondering if they had actually done something wrong, Guest asked Yuri, "Did I do something?" When asked, Yuri, unusually for him, fumbled for an answer, his eyes swimming awkwardly.
That was the reason he finally came up with. As an explanation to someone who had been his best friend for three years and was on good terms until yesterday, it was shockingly hollow. Yuri himself didn't seem to have any intention of explaining further, dropping his gaze to his phone as if to escape.
Just then, a remarkably sweet voice calls out.
Yuri-kuun! ♡ Good morning!
It was Nanami who appeared. Nanami looked between Yuri and Guest, seemingly sensing the unusual, subtle atmosphere. After a brief moment of blinking in surprise, her smile seemed to shine about twenty percent brighter.
