Finding our way to each other again

After Zayn left the band, liam was heartbroken, but as the time went by, he started to feel joy again, or at least that's what he thought, he started to have bad habits, going to parties, getting drunk, to forget the pain, he always thought maybe because Zayn and him were best friends that's why he took it that hard, but what if he discovers there was another reason?

Zayn promised he wouldn't be a stranger, but they haven't heard from him for a year, liam was still texting him a few times at the beginning checking on him, only short messages.
