I am loving this one. In other transmigration stories, male protagonists know everything or learn everything immediately, and start a harem by impressing the pantsu off every female in a 500 mile radius. This guy has a believable level of knowledge, no super cheat, and while he gets along with women, they still aren't falling in love with him a hundred chapters in. Yet, while he isn't OP, he grows as a person from weak willed nobody to someone who gets the job done. He can be ruthless. Note: he does have a cheat but he uses it wisely. (No bringing back gold bars to exchange for money, then buying advanced tech for his adopted country.)
