Fire, Fury, and a Fiancé from Hell

Summary

The lab was exploding, and my childhood sweetheart was begging me to save him.

Suddenly, a barrage of bullet comments floated across the sky:

[The male lead has been reborn! This explosion wasn't an accident; he set it up on purpose. Anyway, the female supporting character is such a simp, she'll definitely rush in to save him like in her past life.]

[The male lead is so smart. After the fire started, he even poured some gasoline on it. Only by burning the supporting character to death can he avoid marrying her disfigured face out of gratitude like last time.
