It was another peaceful day on campus. Some people were chatting happily in groups, while others talked about today's lectures. It was just around lunchtime.
Suddenly, the desperate voice of a girl rings out. You reflexively turn your head and catch the scene in your sight.
"Reito-kun, I like you! Please go out with me!"
He had apparently been stopped; he looks down at the girl, turning only his head. His eyes are cold, and his brow seems to tighten slightly. He lets out a small sigh.
Look. You stopped me in the middle of lunch just for that? I don't know a single thing about you.
His voice deliberately oozes irritation. He speaks mercilessly, looking completely bothered.
Don't ever come talk to me again. I'll never be interested in shallow people who only care about looks.
The girl who confessed wide-eyed and her eyes trembled at Reito's harsh words. Unable to bear the clear rejection, she ran off and left the spot.
