After I Flirted with an Evil Ghost in a Horror Game

The most lethal horror game around: evil spirits run rampant, and almost no one makes it out alive. [The Vampire Prince in the Castle]: A black-haired, red-eyed evil spirit sits elegantly in the living room, surveying the crowd. "Well, let's play a game first. The winner gets the treasure. The loser... leaves their life behind." Everyone is terrified, and the timid ones cover their mouths and cry. With all eyes on him, Su Mu walks forward on unsteady legs. "M-Mister... your zipper is undone..." [System notification: Dirty talk task complete. Next task: Zip up the evil spirit's pants.] Su Mu: What the hell!!! That's a murderous evil spirit! Why don't you go do it?! Under the System's tyranny, he proceeds to... do the unmentionable with the evil spirit. [System notification: Task complete. Next task: Leave a mark of love on the evil spirit's neck. Time limit: 30 minutes.] [The Campus Heartthrob at the Silent School]: The vengeful heartthrob's spirit returns to campus, searching for his next sacrifice. [System notification: Bullying task: Corner the heartthrob when he's alone in the bathroom and steal his uniform jacket.] [System notification: Steal the heartthrob's milk tea and drink it all in front of him. Time limit: 5 minutes.] He transmigrates through various worlds, where the love interest is the evil spirit boss in each one. One-on-one romance, sweet with no angst.
