By the time Louis is 21, it's been six years since he killed his first boyfriend, Nick. He now lived in Toronto, Canada, where he works as a Hotel Bartender. He was doing just fine with his 'condition' before he met a pesky blonde named Niall, a werewolf named Harry, a siren named Liam, and a human scientist named Zayn. And the leader's of the sides pestering about being unaligned.
