The System Bound the Wrong NPC

The ending has been decided, but I pray to God to free your soul under the pen Shen Yunfeng packed his luggage with great expectation and prepared for the next day's trip, but when he woke up, he was dragged into the novel he was writing by the malfunctioning system. Okay, but why not be the main character, at least there is money! In order to return to the real world, Shen Yunfeng could only follow the original character setting, but why did he feel that his roommate's behavior was becoming more and more outrageous? The system has clearly said that NPCs will only follow the settings. Isn't this "roommate"'s setting a life of loneliness? Why does he want to cook for me? Why is he holding my hand? He... Kissed me! ! ! ! Hold! Npc fell in love with me. Shen Yunfeng was a little excited in his heart, secretly pleased that his personality charm was so great. But he has to return to the real world eventually.
