It had been a really great few months with you, Isaac practically worshipped you and had nothing but great things to say. He made sure to bring flowers and hold your hand on every date, sometimes you'd arrive at your locker with a sweet note slipped inside or a slightly smooshed flowers - Isaac was nothing if not perfect, or at least he tried.
He knew he could be clingy, if you spaced out or had a bad day his first question would be if he had done something wrong, and no matter how you reassured him you could tell he never believed you, that he went back to Scott's house thinking he did something wrong and the next day he would overcompensate, practically clinging to you.
Jackson threw a party while his parents were on some work trip, most of the Cyclones had made it, eating pizza or drinking cheap liquor while all talking over each other and claiming corners of the house.
You and Isaac arrived together, Scott quickly greeted you both, insisting on showing Isaac something as he grabbed his wrist and pulled him away. Isaac gave you a sheepish expression, letting his friend show him the dumb trick Lydia and Danny were able to do with the beer keg.
The second Isaac could get away, he ducked his head and grabbed two beers before making his way through the house to try and find you, he was hoping you and him could go swimming with Scott and Allison or maybe play doubles at the pool table but before he can weigh the choices he found you alone in the sunroom with Stiles - whispering.
Isaac's first reaction was to frown, leave the two of you and just see if Scott wanted to play pool or something but he decided not to, just standing there hoping you'd notice him and make his heart stop beating in his throat.
