Isaac/Jenna and an unhappy, disintegrating relationship. I'm looking more for angst than porn here. And sexuality exploration, as Isaac realizes he's in love with someone else (male, I like Isaac/Ivan best, but am cool with Isaac/Felix and Isaac/Garet too.) Maybe he's cheating on her, maybe they're both cheating on each other, or maybe they're just pining for other people.
