Mark and Jack were in the same highschool, hell even in the same class. Jack seemed as if it was by luck, since he always had a crush on Mark, ever since elementary school. Mark was Jack's senpai. He would do anything for him! But then... Jack noticed some people were... eyeing Mark, thinking on making a move on him. Mostly, he sees Ken trying to show his affections for him. But since Mark is very popular, he doesn't have time to really notice him. Jack, knew that he had to either get rid of everyone, or Mark shall never be his!
Jack decides to wait for Mark to leave the school, so he can kill everyone in the clubs, so it would speed up the process. Once it was 3:30pm, Jack spied on Mark to see if he left school grounds. After Mark left school grounds, Jack went over to the Drama club, stole their white gloves that they had on the table, grab a knife from the cooking club, and started his murdering spree. Jack thought "Which club should I 'disband' first?" He went after the Martial arts club, no reinforcements, easier it is to kill them. Jack walked over to the Martial arts club, and killed about 7 students that was there. He sighed, leaving them there to clean up later. Next was the cooking club. "Easy said, easy done" Jack mumbled to him self. He locked both of the doors before killing them, so they wouldnt escape. Jack killed, the 8 students that were there. Finally, Jack was at the Occult club. He did the same process of locking the door, but while he was killing, Felix managed to make a run for it, so he could tell a teacher! But Jack wouldn't allow that... no, if he tells that would be the end for him! So Jack sprints down the hallway chasing him, and throws the knife into his head. Felix falls over dead. Jack sighs, stretching saying to him self "Now time to clean and throw away bodies!!" Jack threw every body into the incinerator, plus his weapon, the gloves and his clothes, and turn it on. Then Jack mopped up the blood and went back home.
The next day was a little bit harder.. cause Ken was always next to HIS MARK! Jack also noticed that there is some students left over, since not everyone joins a club. So he sighs, leading each one up to the roof and throws them off. Making it look like an accident. Now, Jack had a special way of getting rid of Ken... Jack would kidnap Ken, make him so insane that he would just be another mind slave at his disposal. But there was one issue... Ken was smarter then most students at the highschool. So Jack had to think on how to get rid of him.. until Jack had the perfect idea.. Dress up like his senpai, drag him along to his house and tie him up and torture him there! Jack nods his head, thinking that was the perfect plan to get rid of Ken. So Jack stalked Mark until he went home safely and went back to his own home, to get the plan ready and to sleep.
Today was the day!! Jack put on his disguise, and voiced like his senpai. Jack got there early to meet up with Ken. So, Jack asked Ken to follow him, Ken said yes since Ken thought it was Mark. Jack lead them both into a room that had a chest in it, he tranquilized Ken and shoved him inside a box, he sighed in relief of what achievement he has done. Jack runs to Mark, thinking "Finally... Senpai is mine!" Mark looks at Jack saying "Hey Jack! What's up?" Jack felt his face turn red by his appearance. Jack responded "Well... Mark I love you!" Mark felt blush creeping on his cheeks, since he said that his own best friend, loved him. Jack asked "Do you love me back?" Mark sighed and said "Of course Jack! I love you too!" Jack hugged Mark tightly, knowing that Jack can finally call Mark, his lover.
