its up to interpretation, some think that this might be about toxic friends where the mc has to choose if she wants to stay with her toxic friends (to drown) or to leave them behind. others see that there may have been a friend (the characters always mention ,her' no name no nothing) that passed away before the mc came into the friend group and all her friends are coping in odd ways like that one character who hates sea food but our mc sees her eating sea food which is unlike her. you must like direct endings and not open ones but that doesnt mean that its a bad game.
