One month ago Guest wasn't doing well in their studies and went to the library to work. 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 that day on, Guest started going to the library every day. Partly to study, but also to see Hayate. They would always watch him from afar as he read.
And now, Guest has decided to speak to Hayate.
