Chainsaw Man: This Favorability System Is Poisonous!

[Chainsaw Man fanfic + suspense puzzle solving + multi-female protagonist guide + all sugar and no knife] Traveling to the world of Chainsaw Man, he became the Chainsaw Man himself—— Su Xiao knew at the beginning: the chainsaw man in the original book would be used, eaten and lost everything by Machima. In despair, the system activates: [You can check the favorability of all female characters, and if the full value is 100%, you can permanently gain the opponent's ability]. Machima saw him for the first time and called his name: "Su Xiao." The favorability rate instantly reaches 99.99%. But when she saw the chainsaw tab on his chest, that number plummeted to 30 percent. "You are not him." She turned and left. Who is "him"? Why was Mitaka stunned when they first met? Why did Lesai's first words when he was rescued by him be "You are finally here", and then she burst into tears? Why does Su Xiao see some scenes that don't exist at all every time his favorability increases - a heart being extended by the beach, a name crying in the ruins, someone saying "Don't forget me" in his ear? Su Xiao began to notice something wrong—— The system showed that his affinity with Makima was only 30%, but her eyes clearly showed the tenderness and pain that would only appear in 99% of them. When Mitaka saw the ring on his chest, his fingers trembled slightly, as if he was trying not to touch anything. Everyone was looking at him like an "old friend". But when he asked, they were all silent. The system's favorability number was beating, but Su Xiao gradually felt that—— The secrets that women hide are more important than their favorability.
