Please let them be a couple. The merman and the boy, please they just had some shit to go ...

Spoiler

They will be together... Together in the afterlife. The merman will take him with him to the depths of the lake when both are really injured... And that's practically it... Our couple doesn't fight them anymore (after all they have also sustained a lot of injuries) and just leave. And then they go to a hotel to rest and we will get some sweet loving moments uwu

Oh, thats sad but if they're together, its fine. Thanks friend, ╥﹏╥
