Y/N never really remembers how the whole friends with benefits thing came to be with Jay. It just kinda happened, one time at a party. Now everytime either of them feel some type of way that horny itch, they call each other immediately, they drop whatever they are doing to go do it. This never really affected their friend groups..well because their friends never knew. Jay and Y/N barely hung out, they would have small talks at parties and school but other than that they never really talked. Their friend groups never really mixed because Jay had his friends, Sunghoon being his best friend, Jungwon, Jake, Sunno, Heeseung and Niki. And Y/N had hers, Sophia, Elana, Madison and Lara. Even though Jay and Y/N are just friends with benefits they did make a rule. They only have sex with each other, no one else. They can make out with anyone but going any further is off limits.
