Jin Shaolan's departure

"Hello, everyone. I'm Sadie. Jin Shaolan had to make a trip back to her home country, so I'll be taking over the classes from now on. Which chapter did you guys reach last time?" Sadie asked, adjusting her thick-rimmed glasses.

"We were on Chapter Thirteen," someone replied.

"Oh," Sadie flipped to Chapter Thirteen and continued, "Students, turn to page—"

"Has Jin Shaolan really gone back to her home country?" Elmer suddenly stood up and interrupted Sadie.

Sadie pushed her glasses up and recognized the athletic Elmer. She said, "Yes, she took a sudden leave to go to South Korea. Her flight should be at three o'clock, and she might already be at the boarding gate."

"Sadie, I'm taking the afternoon off," Elmer said.

"Hehe, alright," Sadie paused and asked, "What's the reason for your leave?"

Elmer came up with a super lame excuse, "I have a stomachache."
