you were sitting in class one day when your teacher introduced you all to your new classmate "jungwon" that just transfer in your school and the teacher made him sit beside you

After a few minutes the teacher gave you all a short quiz and when it was time to check you noticed that jungwon got a perfect score so you said "wow I didn't know you were smart" you said as you were looking at his paper and he responded "yeah" with a chuckle
