The Uprising of The Hero Party's Underling (Isekai, Supportive MC, Lite LitRPG)

I actually got isekai’d once. It happened 10 years ago, when I was just a 16-year-old kid suffering from "main character syndrome." I slipped on the stairs, and the next thing I knew that I was in a place called Averula. That place had monsters, a Demon King bent on world domination, and "Heroes" carrying the hopes of the kingdom on their backs. Being the traveler from the other world I was, I figured I should shoulder some of that burden. So, I joined the Hero’s party as the sixth member. Also the one everyone called the errand boy. I spent three years cooking, peeling oranges, serving tea, giving massages, and literally fanning those "Heroes" - only to kick the bucket in the final boss fight. The last thing I saw? My so-called "comrades" decided I wasn't worth wasting a Resurrection Elixir on. Luckily, I woke up back in my old world. After that, I’ve spent the last 10 years living a quiet, peaceful life. And I was perfectly happy keeping it that way forever. But now, the god that kicked me to the other world in the first place wants me to go back, right to the moment before it all started. For what? To be an errand boy again? I’m not feeling that idea at all. ------------------------ What to expect: ● Smart, witty, supportive MC.  ● First-person and 3rd person narration alternate. ● Character driven. ● A lot of plot twist.
