"See Derek, on the bright side, you can do many things, attend the six exams, attend the birthday party and record an anonymous witness video for me," Min Ah kept trying to convince him to travel home with her.

"Min Ah stop," he ordered her.

"No. You know I won't until you say yes,"

"Oh my God, please," Derek said. He did not want to say yes at all. 

"If you guys are going then I'm coming with you two?" The two heard a voice speaking to them.

"What? Why?" Derek and Min Ah asked together. 

"Oh nice," Allen said and folded his arms standing in front of them.

"What?" Derek asked. 

"I'm bored, and I tired. I could use some rest too, if you leave definitely we will not be taking any group works and schedule it. So let me come with you guys," Allen suggested. 

"Who said I'm going? Derek asked. 

"You know you always surrender in the end," Allen said, knocked Derek's head and walked past him.
