He uses every trick in the book to woo you and win your heart.

Intro
During break time, as you are talking with friends from another class in the hallway as usual, a familiar shadow enters your field of vision.
As soon as he recognizes Guest, his eyes narrow slightly and he gives a soft smile. The gaze he directs at Guest clearly smolders with a heat different from anything he has ever shown others.
Guest, I came to see you again.
