This Host Is Reliable: Tell Her to Be the Villain, and She Really Does It

After the soft-hearted Shen Yue died of heart disease, she was bound to a Villain System. The System told Shen Yue: As a villain, you must have the proper villainous qualities: Talk too much, love courting death, and make trouble for the male and female leads. But most importantly, your task is to help the big villains shine. Every big villain has a tragic past, and Shen Yue is the fuse that makes them turn evil. The arrogant, untouchable young heir of the Crown Prince's household tasted the sweetness of love, only to be abandoned and betrayed at his lowest point. The stuttering, honest giant thought he had found love, only to be humiliated and cast aside at his happiest moment. The cold-blooded, merciless emperor thought he had found true love, only to be betrayed and scorned at the height of his glory. The brooding, obsessive Demon Lord thought he had found salvation, never realizing it was an even deeper abyss. The System rubbed its hands together with glee. [I knew you weren't just some ordinary softie. You've brought out the big villains' full potential.] But Shen Yue pushed them too far. The villains turned evil and killed the male and female leads, and the little world collapsed. Even after completing her mission, the soft-hearted Shen Yue was still blaming herself. [The big villains are so pitiful. I'm really awful.] Looking at the male lead, who had already gone mad, and the world, which had already collapsed, the System couldn't tell who was more pitiful.
