After a bizarre car accident, the heroine, Lin Jianxing, is reborn three months earlier and discovers she can see the constantly updating “Dangerous Bullet Screen System” inside the hero Pei Chen’s mind. The comments reveal his possessiveness, corruption level, and plans in real time, and sometimes even give her advance warning of accidents about to happen. On the surface, Pei Chen is a restrained and aloof, refined and highborn tech company executive. In reality, he’s a lovesick obsessive who disguises his desire to control her as concern and his jealousy as care. To uncover the truth behind her death in her previous life, Lin Jianxing has no choice but to pretend she knows nothing and use the comments to avoid danger and stay alive. The more she tries to evade him, the more closely Pei Chen watches her.
