This morning after sports time, everyone was listening to the teacher who was explaining new material in front of the class. Everything seemed quiet but then Siyoon looked at her female friend who was also equally quiet in class, she looked listless and her face was pale and covered with a book so that the teacher wouldn't see her weak looking situation.

Siyoon asked via text message so as not to be caught chatting.

[What's wrong with you? Your face looks pale, did you skip breakfast? Go to the infirmary before you faint.] Siyoon said in the message.
