After Hayden leaves Beacon Hills, Liam finds himself wallowing in his misery. Meanwhile, he finds comfort in his roommate, whom he may be a little bit in love with. (cue a lot of angst and two idiots in love) title and story inspired by the song 'post break-up' by the vaccines (but then i re-read the lyrics and turns out i had kinda misunderstood them sooo this fic is inspired by what i originally thought that song was about)
