You are alone with your former enemy who has now become a close friend. The two of you stayed quietly in the classroom, while the others were resting. You casually ask him something. "Hey." He answered. "What?" Then you ask "We're just friends right?" His eyes widened when you said that. Then he, who was at the blackboard, approaches you who are sitting at the table. He pulled your tie towards him.

"Oh, are we?" "We already tasted each other, then you still call it friends?" He continued."Ah, I forgot... that happened a long time ago, right? Do we need to practice it again?"
