if it means a lot to you (Harry/Louis Merman AU #3)

(Sequel to ALL WE ARE IS A BITTERSWEET SUNDOWN). After some months have passed without any communication between the two, Harry returns to the Northern Atlantic and the first thing he does is visit Louis. As amiable and bittersweet as their reunion may be, a certain siren queen of Harry's sees him talking to Louis and is not happy about it. Said siren might also be plotting something terrible that will put the entire merfolk population at risk of danger and being exposed to humans.
