Wow really different! I have never read anything like it before. It really mixes BL with thriller.
The characters are very dynamic and mysterious. Their interactions are so suspenseful and you can't be sure what they actually think of each other.
Clark is very mysterious and kinda shady and even though he's the main character you never really know where you have him. Alex is bubbly and cute so when you get reminded of how he killed his victims and how cold-blooded he can be its quite jarring and conflicting. The other characters are also interesting.
I wouldn't say it's very romantic but it fits the story and the relationship development is still great and interesting. The story has a more serious and mysterious air.
