Their first time is under dubious circumstances. Raymond unknowingly drinks an aphrodisiac-like-drink at the event they investigate and the effects eventually show up while they’re the only two in the police station. Oliver goes to... lend him a hand but then it leads to lending each other a hand. Ahem. It happens a second time again under similar circumstances mostly started by the aphrodisiac effects and it leads to more.

The novel ends in a sort of but not quite open ended way? It can be taken both ways, I think. To me personally, it’s a perfect ending. But I read some reviews on Japanese websites, and I guess the ending makes people wish there was a sequel. I can see the possibility of a sequel happening, but in my opinion it would kind of drag out the story instead. So to me, I like how the novel ends. It has the right amount of everything and doesn’t lack anything!

Like literally the moment they said there were 3 demons on the scene, instead of one, I had it figured out who the 3rd demon could be.

(MC was obsessed with ML since young) and I wish they had slightly more history (like a past!relationship would've been cool), but MC had fallen in love at first sight and that was the only interaction they had (they didn't even speak! ML didn't even know MC existed!) before they met as detectives.
