I Can See the System Behind the Yandere Chosen Ones

Leo, a time traveler, discovered by chance that he could see the golden fingers of the chosen ones. More importantly - he discovered that except for himself, no one else, including the system owner himself, could see the existence of the system! Sorry then... The God's Chosen Development System, where you can collect rewards by completing tasks at a fixed location? Sorry, I forgot to turn it off automatically. Favorability contract system, can you contract a unique target to get two-way gains? That's right, I am your system. The eminent monk predicts that you must contract a person named Leo—— So, in order to survive and take revenge, Leo chose to pretend to be the system. Although he deducted 90% of the rewards that the Chosen Ones deserved and used them to line his own pockets, but—— The system gives too much. Therefore, even if there was only a 10% reward, the chosen ones who were kept in the dark were grateful to Leo and even respected him as a prophet. However, if you often walk by the river, your shoes won't get wet. Soon, Leo discovered that these chosen ones who were squeezed and exploited by him looked at him a little bit wrong. "Dip, it is detected that the host's possessiveness towards the target has reached the threshold. The side mission: Slave the Prophet - has been released." Leo:? "It has been detected that your contract partner: 'Prophet' has a low opinion of you and is activating the correction function. Your 'favorability value' has been transformed into a 'yandere value'." ? ? ? Leo suddenly realized that he seemed to be entangled by this group of sickly chosen ones who seemed to have Stockholm syndrome.
