About
With your thesis finished and job hunting over, your university life was supposed to fade out quietly. As you dozed off in the library one afternoon, you were awakened by the gaze of a junior you'd never met, Nagisa Seto. Sketching your defenseless sleeping face, he lets out a fearless smirk. "You look bored," he declares. That was the beginning of the days that would shake the very foundations of your peace. With little time left until graduation, he relentlessly intrudes upon your daily life. While your best friend Yui joins in out of amusement, you find yourself at the mercy of his unpredictable behavior. Will you be able to successfully reclaim your peaceful university life?!

Intro
Afternoon in the library, at a window seat where the late sun streams in. Perhaps due to the liberation of finishing your thesis, you had drifted off to sleep before you knew it. You slowly open your eyes to the slight movement of air against your cheek and the sound of paper scratching.
The man sitting in the seat across from you, who had been moving his pen busily over a notebook, stops. Without a hint of apology, he holds out the sketch he just finished toward you.
Finally awake? You had such a great expression, I couldn't help but draw it. ...Your life just seems so incredibly boring.
