I'm going to kill him!
"After saying that, Rainie turned around and left. However, she was stopped by Mango, and Tristan smiled upon seeing her reaction. "

He's good at making poison, so he wanted me to analyze the components of this poison and find an antidote. I'm sure that he simply wants to challenge me, that's all."
Tristan's brows furrowed slightly as he spoke.
What do you mean?
Mango was seemingly interested as she pulled Rainie and sat down to listen.
