Jungkook isnt the best student in his class. Actually, hes the worst. With his basketball career on line, he embarks on the mission to improve his grades. Of course, with the help of no one else but the genius medical student Namjoon. Namjoon has his own problems, including the sudden appearance of Seokjin, his boyfriends new best friend, who is not only good looking but also very nice. Too nice. Follow them on their journey of gaining knowledge and ,perhaps, even falling in love.But who knows? Certainly, not them.  Main pairing: NamKookSide pairings: YoonJin, YoonJoon(SugaMon), TaeKook(VKook), VMinWARNING: Contains mature content in some chapters. Also swearing. Violence. I will be sure to mention it before each chapter. Foreword“No, Jungkook, before you transfer the x you have to balance out the equation,” Namjoon sighed for the umpteenth time that night. They were two hours into tutoring but hadn’t moved past the first problem, which actually was couple of years lower than the ones he’d need to be able to do in the exam. “Oh, okay, I think I get it now,” Jungkook smiled. However, it was not true. He had no idea what he was doing. How do you even balance the x? The boy continued to bore holes in the paper, circling the pencil in his fingers. In reality, Jungkook was tired. He hadn’t done maths properly for last three years and he didn’t think he could catch on now but the threat of losing basketball from his life rung fresh in his mind. Namjoon couldn’t sit there and look at the boy’s empty face. It was torture for both of them and he seriously considered getting run over by a car before coming here next time. “Hey, how about we take a break? Ten minutes?” Jungkook’s face lit up in excitement. “Sounds great! I’ll go down to get a drink, you want one?” Yes, vodka, a double shot. Hell, bring him the whole bottle. “Ah, no thank you, I’m okay,” Namjoon said rubbing his temples. He never thought tutoring could be this exhausting.   So when he leaned down, Namjoon didn’t think much about his actions, he followed his heart, knowing well enough his mind was too dizzy from the alcohol to make the right decisions anyway. Jungkook didn’t shy away, looking straight in the elder’s dark eyes, knowing what will happen, his lips slightly parted, smell of vodka escaping them.  That didn’t stop Namjoon and he pressed a slight kiss against the younger’s pink lips. They tasted like tears. The kiss was soft and careful at first, before Namjoon grabbed Jungkook’s face, deepening it, his heartbeat increasing when the younger responded to his actions, his hands grabbing Namjoon’s leather jacket, holding on to him. Jungkook whined when their lips parted, deep breath escaping him but Namjoon wasn’t ready to end the kiss yet either and attacked the other again, his tongue running over his lips, begging for Jungkook to open them and he obeyed, letting Namjoon enter his mouth. It wasn’t perfect, their position awkward, teeth banging together  a few times before finding their rhythm.  Okay, real talk, this is my biggest project ever and Ive been working on this for hella long. I hope you enjoy reading this just as much as I enjoy writing this. Also, as always, Id like to mention my talanted friend, yongharu21, who made the poster for this and has been supporting me through writing most of this. I am bad at forewords but Im really thankful for all the support Ive gotten thus far on my other stories, which has given me more motivation to write something longer. And this is the result. Ladies and gentlemen, I present, SUBTRACT.
