I liked it, but struggled with a few things. Jonah's feelings for the junior high crush - then and now - made sense to me. Sebastian's feelings for Jonah made less sense, and I don't think it was just because we weren't in his head. I just never got why he'd have been interested in Jonah in junior high, why he'd have remembered him all those years, or why he'd be interested now. Perhaps it was because Jonah was an unreliable narrator, but ideally the reader should be able to see and understand those things through other characters' words and actions, even if the narrator himself is oblivious.
