I've read quite ahead in the web novel.
Just so everyone knows, the protagonist's night life doesn't get any focus at all. Just assume it happened if the writer said it does. Some relatively interesting developments happen here and there but the story steps back from its character focus a bit more and goes on a more macro focus. Not to say new and interesting characters don't show up. You'll get some revelations about Lulushi the vampire, and about angel society and stuff so it's still got some interesting developments ahead.
