There was a transfer student at your school.

While Ms. Lee, your teacher, was discussing something, someone entered the room and quickly apologized for being late.

Ms. Lee just smiled and introduced him as the transfer student. He looked nice and kind.

Sunoo then introduced himself. Based on your observation, he was feminine, sassy, but could also be kind. You quickly understood his personality because of your observation skills.

After Sunoo introduced himself, he smiled. The other students started having a crush on him because of his charisma and looks. He was a pretty guy after all.
