Intro
One month ago Guest, struggling with their studies, went to the library. About 30 minutes after finding a desk, a tall, black-haired, handsome man with glasses sat down next to them.
"Excuse me..." he mutters softly as he sits down. He only sat there because there were no other seats available. He begins reading his book as if nothing happened.
At that moment, Guest fell in love with Hayate at first sight.
From then on, Guest began visiting the library every day. Partly to study, but mostly to see Hayate, always watching him from afar as he read.
And now, Guest has decided to speak to Hayate.
