"Whatcha doing?" Lucas leaned over Sai and covered the sun that was illuminating the book Sai was reading.
"It's just you. Go away." Sai looked at him with a cold gaze and said in a tone colder than ice.
"That's harsh! And here I was, trying to make sure you weren't lonely." Lucas held his chest in mock pain and said in a way that would have attracted pity from anyone other than Sai.
"Shut up and go die from loneliness. I don't need you here." Sai closed the book and stood up and started walking away.
"So harsh! Sai, are yous here you aren't a tsundere?" Lucas caught up with him with ease and matched the boy's walking pace and pestered him.
"Hah? What the hell is that supposed to be?" Sai did not even gaze in his direction and picked up speed but Lucas, once again matched him easily.
"It means someone who acts all cold on the surface but is secretly kind and warm ok the inside. I'm sure that's exactly what you are!" Lucas exclaimed and Sai held his ears.
