It sounds like you like Doujin novels from Douluo Continent ~ I'm a cute recommendation expert who likes to recommend novels a lot. But I'm not good at recommending harem novels, but I can recommend a few Doujin novels that I personally think are good. I hope you like them ~"Ke Xue Descends Douluo","I Can Control Time","The Legend of Divine Snow","The Omniscient Library". These novels are all finished, so you can read the entire story without worry. I hope you like my recommendation, Mwah ~๐
