I can recommend you a fantasy novel with a male protagonist who is very loyal to his feelings and who grows stronger step by step. That is the Legend of the Mortal and the Defying Immortal. Although Lin Kong wasn't a genius, he had relied on his treasure, the "Spirit Gathering Flask", to reach the peak step by step. His principle is "I won't offend others unless they offend me. If they offend me, I will punish them." He is also devoted to relationships, so he completely meets your needs! I hope you like this fairy's recommendation. Muah ~😗
