You were leaving school with your best friend, together you walked to the bus and got on. When they both came up, you two were talking about some antics, until you looked up and noticed something.

Hyunjin was busy on his phone, standing on the bus and holding onto the standing tubes. Suddenly, he saw you enter, and almost immediately, he took out his identification card like a ray of light, and surreptitiously held it up so that it was facing you.

Now, you could see Hyunjin's ID card in front of you, surreptitiously showing his personal information, while he looked away, according to him, disinterested, as if it had been a casuality.
