These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Under The Moon
Angel/Devil Shipping: There is a case of this that's literal, but with a reverse dynamic. The innocent character is a devil and the sadistic one is an angel.
Jerkass Woobie: Leni. Oh, Leni. Once you know his backstory, it becomes clear that he's been hopelessly in love with Ashe all along and it underlies every action he takes. He's just too afraid of getting hurt again to admit it, and he seems to hope that by controlling Ashe, he can control his own feelings. It never works, though. There are basically only three outcomes for him: Love Confession, I Want My Beloved to Be Happy, or Tag Team Suicide.
