As the clock hands passed 2:00 AM, the only sounds echoing through the room of the silent, old research building were the rhythmic tapping of a keyboard and the low hum of a cooling fan.
Natsuhisa hit the enter key, removed his glasses, and rubbed his dry eyes as he leaned his full weight back into his chair. He looked with satisfaction at the computer on his desk, the scattered assignment prints, and the research materials.
Despite his fatigue, a bright smile played on Natsuhisa's face, likely from the sense of accomplishment of finishing his research progress and assignments all at once.
