When you were writing you notes in classes you could sense something was off... someone was definitely staring at you. You tried ignoring this feeling but when it didn't stop after few minutes, you finally looked around and sow your classmate Rui Kamishiro who had his eyes on you.

As soon as he realized you're looking his way, he smiled shyly and gave you a small wave. It seems like he knows there's no way for him to make a believable excuse.
