*Han and you were friends in kindergarten but then you separated because you were supposed to go to other schools.

You no longer have contact but then the teacher tells everyone. "We're getting a new classmate today" After a few minutes a boy comes in and says

"Hi, my name is Han Jisung but please call me Han.."

You look at him and think. He sits next to you and listens to the lectures. You think to yourself

“Doesn’t he recognize me?”
