This book is also known as The Tentacle Witch Won't Die at the Hands of an Abnormal Transmigrator.
Protagonist: "You think you're good at fighting? So what? In Norland, you need power and connections to get by. Who do you run with?"
Player A: "I'm A Jie. Come hang out at my place. I live alone, and it's pretty spacious."
Protagonist: "Oh, so you're pretty brave, huh?"
Player A: "You bet. I'm super brave."
Protagonist: "You stole offerings from the temple, and your friend slept with the lord's wife. Fine, everyone makes mistakes. But you made me fail my mission and miss out on the reward."
Player B: "What, can't we just pay you off?"
Protagonist: "Honestly, I don't care about a few gold coins. Sigh, you wouldn't understand, but you've ruined my reputation. I can't just let that slide, or how could I hold my head up at the Adventurers' Guild?"
Player A: "So what do you want?"
Protagonist: "Simple. Help me deliver something to a friend."
Executive: "So this is your trick for conning beta testers into delivering a bomb, then killing rule-breaking transmigrators?"
Protagonist: "The mission was completed, so it's a HAPPY ENDING. The players got their compensation packages, and I took out my target."
