After a Background NPC Became a Vicious Cannon Fodder

[Schoolyard Supernatural Cultivation, Tsundere Harem Magnet Protagonist] Shi Changhuan transmigrates into the role of a cannon-fodder villain in a brainless game he once played. He has to complete the daily missions and reach the bad ending to return home. In the bad ending route, the cannon fodder is jealous of the male lead's wealth and good looks. Taking advantage of his position in the student council, he targets the male lead every day and drives him up the wall. So, after returning to S City, the male lead has the cannon fodder beaten to a pulp before dawn. From the start, his father is run over and killed, his mother packs up and runs away, his grandmother is seriously ill, and he is left broken and stuck with a damnable System. Shi Changhuan: "..." Damn, what kind of hellish start is this? He struggles to survive until he's fifteen, finally meets the male lead, and figures he should finish the missions as soon as possible and get this over with. But what he never expected was that this male lead seems to have something wrong with his head. Outside the office, Shi Changhuan gleefully picks up the script for courting death and treats the wealthy, overpowered male lead with icy disdain. The male lead thinks shyly, "He's so special. I like him so much." Shi Changhuan: ? At the school gate, Shi Changhuan abuses his authority and snaps viciously, "You didn't bring your access card, so don't even think about going in." The male lead is overjoyed. "Are you secretly giving me a day off? Deskmate, you're way too good to me! I heard everyone else has to write an 800-word self-criticism. I knew we were the closest buddies!" Shi Changhuan: ? Downstairs from the dorm, Shi Changhuan grabs the male lead by the collar and sneers at him. "You want to be friends with me? Who do you think you are?" The male lead blushes shyly. "Deskmate, you're so handsome!" Shi Changhuan: ? Get lost. And so, the blunt childhood friend who mocked him in the original story personally gives Shi Changhuan a love letter: "Changhuan, I want us to be best friends for life!" The S-rank executor who was supposed to personally put an end to him bends down and gently kisses the back of his hand. "You may not know this, but you are my four seasons." The lovesick, obsessive younger brother who became consumed by revenge against him in the story gazes at him with an intense fixation. "You were the one who pursued me first. What gives you the right to just leave?" Even the System, which usually finds every opportunity to insult him, speaks tenderly. "I came here for you all along, Huanhuan." Shi Changhuan: ? His life was supposed to be one where his family and friends loathed him, his teachers were disappointed in him, and everyone abandoned him. Instead, Shi Changhuan turns it into a story where, by day, everyone adores him, flowers bloom at his feet, and people look up to him, while by night, he hunts ghosts and demons with a whole crowd of underlings. No... Wait, what? He doesn't know how to hunt ghosts!!!!! Why is everyone looking at him like he's some big shot???? Shi Changhuan is exhausted in body and mind. Please, leave me alone... I'm just a cannon-fodder character. Wait, no! I'm just a cannon-fodder character, right? [Content Warnings: 1. The protagonist is doted on by everyone and is a harem magnet.
