Its manga about adult fears colliding with childish dreams, so its actually a toss up if they stay in Bali the whole time. If he literally orchestrates an absurd murder plot to make her die at her happiest, do an absolutely unhinged bonnie clyde arc robbing banks in Bali, or legitimately just get away with it because they threw the cops 10k yen bribe. In short I love this story, it just keeps on getting more and more off the rails.
