[The food had arrived and Mijoo started to eat while Yoojin sat there]
Yoojin : eat, the food will get cold.

Mijoo ate and Yoojin just looked at her eat peacefully there. After lunch, she took Mijoo back to school. When they arrived at the front entrance of the school, Mijoo's teacher came out to greet the students inside of the school. Mijoo ran inside of the class back to her education while Yoojin and the teacher got a chance to talk while standing there.

Yoojin : i'm sorry about Mijoo leaving in the middle of school time.
Teacher : did something happen ?
