THAT'S IT?! Σ(  ̄□ ̄||)
Also when did he refuse Karyan's route? I don't even remember that.
And why do I feel like this rushed ending is more of a "I don't want to do this story anymore" than a "the series was canceled"? ( ̄へ ̄)
There’s a scene in the novel that happens sometime after Jerry returns from the beach vacation. He goes back to his parents house for a few days, where he receives the red gem from Karyan. I don’t know what exactly went down (read the MTL), but it ends with Karyan’s route being dissolved.
Hope that answers your question.
He's suffering
