Living a loving life

Kevin was an average boy of his age. He strived for his grades, pleased his parents for additional allowance and dreamed of having a girlfriend before he graduates college. Until suddenly a system came in his life. First Meeting [Hello Host!] “Da fuck?!” [Wow! You’re too smart! How did you know my nickname host?] “That is your nickname? Who the hell named you that?” [The main system. He said that he accidentally had an accident when I was born. So he ended up setting my name as “Da fuck”. When he was calm enough he made a remedy with my name. But the first name cannot be changed so it is now my nickname to override the error.] “How poor you are to bear that name when you are born. Since you are renamed, what is your new name?” [System 0B163: A good guy system.] “....you know what we should just stick with your nickname. It’s less harmless and more inclined to my mood now. For someone who wants to have a relationship you’re just too much of a flag.” [Understood] Nth period later “You know what I should just sever my ties with you back then” [Why Host?] “Although I achieved things that men dreamed for all their lives, you are just too good at planting landmines for me.” [I think I haven’t done any of that sorts host.] “....then how do you explain these fighting monsters who aim to keep me? I remember not asking this for the love of my life!” [Well wasn’t that a man’s romance? The intelligence I got says that much.] “Da fuck!” [Do you mean to call me host?] With a system that is just too good to be true, Kevin shatters his mundane life in the journey of being a good guy. Author's note: The harem is slow to build up in this story but the number of them is already decided. I am also undecided of making this an R18 story. But for sure there there will be gore somewhere in this story.
