After Transmigrating into the System, I Was Driven Crazy by the Host

Entering the lowest level cute system, I thought I would work hard to lead the host to become an immortal. As a result, the immortal sister who was bound was cold and dusty on the outside, but soft and cute on the inside. Others' tasks are to slay demons and change their fate against the will of heaven. My task is: Dance, have a meal, be cute and socialize for a while. The system level keeps rising, all thanks to the funny value. Later I found out, She seems aloof, but she leaves all her tenderness to a system that will only cheat her. "Stop upgrading, I'll support you."
