This starts after the last chapter. I've already planned the entire story out so these are just the summaries I have saved.

Chapter 19 - It's still summer and you spend a day at the orphanage with Baekhyun and Luhan since you asked if they wanted to come. Chanyeol wanted to but already had plans. At the orphanage, Baekhyun and Luhan discover how kind and gentle you are. Beakhyun thinks you have two different personalities since you knows your secret and hasn't told anyone about it yet. 

Chapter 20 - You, F(x), and EXO all go paintballing. You all split into groups. You are in a team with Chanyeol, Amber, Xiumin, D.O., and Sehun. Baekhyun, Kai, Sulli, Victoria, Tao, and Kris in another. Luhan, Chen, Krystal, Luna, Suho, and Lay in another. In the end of the game, you and Luhan are left remaining and you try to shoot each other. He lets you win so his team has to treat the rest to lunch. While out to lunch, a black car rolls down it's window and a person watches from afar.

Chapter 21 - Another school year begins and you give your speech as class president. You go to your new classes and discover that you have the same Chinese class as Luhan. That's how you get closer to him and become better friends. During lunch time in the library, you're chatting with Babyfacelulu once again. One thing you don't know is that the person you're chatting too is also the person sitting across the table from you, Luhan. While working on Chinese homework you let Luhan view your screen to check your grammar and Luhan sees your chat box with his id in it which surprises him. 

Chapter 22 - You're on a mission working behind the scenes and hacking into security cameras. You see an unfamiliar spy in one of the videos who looks like Luhan. You see a Band-Aid on his forehead in which you remember Luhan had from an accident that occurred in class. You start getting suspicious and realize that Chanyeol could have been the tall spy you've met on a mission and the other spy could either be any other guy in EXO.

Chapter 23 - You're on another mission which you know the other spy you meet is Chanyeol. Because of a stupid mistake he does, you accidentally shout out his name which startles Chanyeol. Everything is spilled out of the jar. You know about their spy organization and they know about yours. 

Chapter 24 - After staying after school to finish up work you walk home alone in the dark. A mysterious car follows you and you try to lose them from trailing you. Your door bell rings and you're surprised to see Daehyun (You past crush/neighbor). He tells you that he's moved back and that he lives in the house at the end of the block now. You fall for him all over again and he introduces you to his friends (BAP). 

Chapter 25 - You start hanging out with BAP more often than EXO and f(x) now. You start changing as well such as getting distracted from school work and your missions. Luhan, Baekhyun, and Chanyeol all get jealous since you don't hang out with them anymore. Baekhyun tries talking to you but you argue with him which gets the two of you to not talk to each other at all. 

Chapter 26 - At school, you were walking with Daehyun. Someone accidentally pushes you and you land, down the stairs on top of Daehyun. He brakes an arm for you and you feel really bad so you end up helping him out a lot. Daehyun wants to watch a movie with you and you agree. He persists you to watch it at your house and you let because his housemates are at his house. You needed to go out and buy popcorn because he's the guest and his arm is broken and you told him to make himself at home. When you're gone, Daehyun checks around the house and discovers your spy room. He looks over your things. As suspected, he confirms that your a spy to his spymates.

Chapter 27 - Your uncle tells you that Sehun is your long lost older brother. He was able to escape the fire but your parents weren't able to. You drag him out to get ice cream to get to know him better. While eating ice cream, you dropped some on your shirt.  He goes back to get napkins and tells you to stay there. When he comes back, he finds you getting dragged into a car. He quickly memorizes the car number and follows it leading to an abandoned building. He calls the rest of the guys but the phone dies right after he tells them the car number.

Chapter 28 - Sehun is there and tries to save you but you're tied up in a chair. You release yourself but you and Sehun are beaten up by the bad guy. You found out you were being betrayed by Daehyun and you've fallen into his trap. The bad guy was Eunsik. BAP was on his side. He said he burnt down the organization your parents were in together and thought he had killed them along with Sehun. He realizes that the didn't and he aimed the gun at Sehun and you rushed in front of him.

Chapter 29 - (BAEKHYUN ENDING) Before you went out to get ice cream with Sehun, Baekhyun texts you saying he was sorry and he confesses that he loves you but you never read it. The bad guy had taken your phone and looks at your unread message from him and reads it too you. Now not only your entire body hurts but also your heart. That's when you realize your feelings for him. The bad guy pulls out his gun. You hear someone scream out your name before the bullet was shot. It had landed on the side of your head. The next thing you knew you're awake in the hospital after a 6 month coma. Baekhyun had been taking care of you while you were in the hospital and he's the first person you see. When he finds you awake, you confess to him too then happily ever after~

Chapter 30 - (CHANYEOL ENDING) Chanyeol just follows the tracking of the license plate number Sehun told him to the abandoned warehouse with the rest of the members right behind him. There, you were trying to cover Sehun from being shot but just in time, Chanyeol run towards you and protects you from the bullet. A fight breaks out while you cry over Chanyeol trying to protect you. Chanyeol suddenly confesses his love for you as if he's going to die and you tell him he isn't going to die and that he's an idiot. In the hospital after winning, Chanyeol asks you what your answer is and you awkwardly say yes to him. Another happy ending :)

Chapter 31 - (LUHAN ENDING) Luhan shoots the bad guy from a distance which made him miss shooting at you. B.A.P. confesses that they joined only because that's what choice they had left to survive but are still put to custody. Everything is at peace again but EXO-M has to go back to China. You send him off at the airport. While he's gone, you realize how much you miss him and he misses you as well. Three years later, you're on a mission and you encounter a spy and you recognize it to be Luhan. Ta Dah~

So that's pretty much how the story goes. Hope I didn't bore you out. Good job if you read it all. ^^
