I think they'll wake up, realise what frightful cunts they've made of themselves and just creep under the nearest brick to sob and cringe.
They'll separate after she fucks her best mate who always pretended to be gay and he has a fling with a girl who's identical to his mooning identikit girlfriend. They'll blog the breakup in the most bilious way imaginable then lose interest as a new fad will come along to engross their shallow minds, but years later these hideous images will bob to the surface like the bloated corpse from a dreadful era and haunt them forever as people scream with hysterics about what utter, utter arseholes these people used to be and probably still will be.
