I know killing characters will make the story more thrill. But I don't think it will work with this one. 2 deaths are enough. More will make it a mess.
If you wanna kill TOP, I think you should let him live till the end. I love the idea of killing all the main characters at the same time in the end. TOP, Young Bae, Ji Yong- everyone that involve this case.
That's just my opinion. Sorry if you find it disturbing~

Let Top helps Youngbae to solve the mysteries!

Always kill.

YEEEEESSSSSSSS

DONT KILL POOR TOP OMO :C
