New semester... That means new class, new friend. A girl in her 17th standing in front of a message board looking for her name. From her nametag, Kim Hanna is written on it. Students that are there are starting to murmuring about their new class or new teacher. 

"Ya, Hanna... I think we are in the same class again." Hanna's friend said while taking a picture of the name list.

"Yeah..." She answered her but she doesn't look at her. Her eyes are still scanning the name list and stops on a name.

"Not same class again." She said under her breath.
