Contracted Twin Succubi, I Have Become Their Power Bank

I'm just an ordinary high school student. My dream is to get into a decent university. I appreciate the "study materials" of my classmates from time to time. Until the day of evening self-study, the devil invaded and the heads of the whole class exploded like watermelons. I narrowly escaped, but was forced to "adopt" two succubus roommates who couldn't get rid of me. A coquette and a cold beauty. What's even more outrageous is that the official organization came to my door and told me that I was no longer a human being, with a monthly salary of 500,000 yuan, five insurances and one fund, and a full-time responsibility for dealing with demonic incidents! Now, my left hand wants to replenish energy for the succubus who is waiting for food, and my right hand wants to answer the old Nokia's reminder mission. I just want to ask: Can I take leave from this job of saving the world?
