- 5 minutes ago - 

From: Kai
To: Yixing
I need you to stand outside the girl's washroom.
Dont let ANYONE in. I trust you Lay.

Yixing sighed heavily and stood up.
Yixing: Jongin needs my help so I need to go. I'll see you later Joonie. 
Yixing turned to Suho and smiled. Suho returned the smile and waved goodbye. Suho turned away and continued to talk to the others until he felt his phone vibrate in his pocket. 

From: Soo
To: Suho
HYUNG! HELP
GIRLS WASHROOM 
NOW

Suho stood up, surprising the others.
Suho: Ah, Im sorry. I need to be excused for a few minutes. 
Suho walked out of the cafeteria and ran to the bathroom. Dont worry Soo.. Your unni is coming...

As Suho was almost at the washroom, he saw Yixing standing outside the door.
Suho: Yixing? 
Yixing turned to Suho.
Yixing: What are you doing here?
Suho: I.. uh.. need to use the washroom.
Yixing: Im sorry Joonie but I cant let you use this washroom. 
Suho: Why not? 
Suho walked towards the door but Yixing stopped him.
Yixing: I was told too. 
Suho didnt care if Yixing was told too, he wanted to save Kyungsoo. 
Suho: I dont care Yixing. Now let me through.
Yixing stood in front of Suho and shook his head. 
Suho: Oh my ing gosh Yixing. Move! 
Hearing Joonie swear for the first time made Yixing flinch but he still didnt move. 
Suho: I will f-
Suho was cut off when he saw Kyungsoo and Kai exit the washroom together. 

- Now - 
Suho: Dont ever go near that boy again Soo. 
Kyungsoo: Joonie, its okay. You dont have to worry about me. 
Suho stopped and faced Kyungsoo.
Suho: Soo, your parents trust me to take care of you. I promise them I wouldnt allow anyone to hurt you. 
Kyungsoo knew how close his parents used to be with Suho's parents. He was a brother in the family, but ever since both their parents died in a sudden car crash, they both were never the same. 
Kyungsoo: I know Suho.. I know..i just.. Lets just head back to class..
Suho nodded and released his grip. 

- After school - 
Suho waited for Kyungsoo to finish packing his books. He looked at Jongin, who was smiling at his messages. Then he looked at Yixing, who was sitting still.
Kyungsoo: Alright, lets get going unni. Did you call Kyuhyun yet? 
Suho looked back at Kyungsoo and nodded. 
Suho: Let's go get the others. 
Suho grabbed Kyungsoo's hand and walked out of the classroom. 
Yixing: I really hate you Kai.
Kai: I love you too Lay. 
Yixing stood up and sat on Kyungsoo's desk.
Yixing: I cant believe you blew my chances with her. I really liked her.
Kai snorted and faced Yixing. 
Kai: Dont worry. You and me, we'll get those girls.
Yixing relaxed his back on the chair and sighed. 
Kai: I know this is unusual of me to ask but.. Lay, what if Joonie and Sohee arent who we think they are? 
Yixing sat up and stared at Kai, who was staring down at his phone. 
Yixing: Whatcha mean? 
Kai: I dont know. I get a different feeling whenever Im near Sohee and her friends... Nevermind. Lets just go home.
