Netori: I Shall Steal All Of My Enemies' Women For Revenge!

Haruto looked up at Daiki, who, to him, was like one of the world's unsolved mysteries—impossible to predict, impossible to understand.

'Is he crazy? Was Ren never important to him to begin with?' His frown deepened as he weighed the bat in his hand.

It was the same bat that had sent him to the hospital when he fought Daiki. And now, that very weapon was in his grip, meant to send Ren straight to hell.

Yet, despite his advantage, irritation churned inside him. 'So all my effort to take Ren down was pointless?! All my time and Ayaka's sacrifice meant nothing?!'

For some reason, the urge to beat the shit out of Daiki instead burned hotter than his hatred for the pathetic wreck in front of him.

Ren, bloodied and gasping, was no longer a threat—just a man screaming and cursing at the one who had trapped him here.

"I BECAME YOUR LAB RAT FOR YOU TO TREAT ME LIKE THIS?!"
