I Broke Up with Merlin [Crossover]

In his previous life, Cyril was King Arthur's half-brother on his mother's side and the younger brother of the witch Morgan. As a duke, he was powerful and influential. Apart from his frail health and early death, he was perfect in every way. Though his life was short, history and legend had a place just for him. In this life, Cyril became an unknown magician. He had neither power nor influence, but he reached the pinnacle of success by opening an online shop selling magic potions. Cyril's potions sell widely across other worlds, and ninjas, heroic spirits, yokai, tsukumogami, heroes, and many others all praise them. ...Except that the occasional quality issue gets him customer complaints, and the online idol he dated for two years, Magic Merry, turns out to be the online scammer Merlin. His life is still absolutely perfect! Cyril: Even if the potions I sell have all kinds of side effects and my customers give me countless furious bad reviews, I absolutely ...will provide my dear customers with prompt after-sales service whenever they need me. Yes, that's professional integrity. ══════════╮ [Read this about the story]╰☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆ * Joining the paid platform on September 5.
