Slay the Dragon? I Don't Want to Do It a Long Time Ago

(Western fantasy, decisive killing, dragon slaying, team battle, multi-racial, slow-burn, pure love, single female protagonist) Sevion Cole: I really don't want to fight and kill. I will return the money to your Dragon Hunting Club. I don't want my wife to find out that I am still in this industry. "Now you want to wash your hands in a golden basin? Why did you go there earlier! Remember, a dragon knight who is afraid of dragons is not a real dragon knight." Cole had no choice but to go back to his old career behind his wife's back Leola, Queen of the Dragon Clan, kicked her away: "You really want to die. How come I slayed dragons before I met you, and I'm still slaying dragons after I met you!"
