The Protagonist's Useless Brother

[A/N: No SMUT.] I died from overwork as a life coach. I got transmigrated into a fantasy novel. Standard stuff, right? Wrong. I woke up as the useless older brother of Theodore, the dense, battle-obsessed protagonist of “Destiny's Harem Knight.” The world is doomed to fall to a Demon Lord unless my brother forges alliances by marrying his four destined heroines. My mission is simple: use my life coaching skills to guide my romantically-challenged brother and save the world. The problem? My “help” is working a little too well... on the wrong person. Now, his stoic teacher, his fiancée's powerhouse sister, his rival's legendary mother, and a 500-year-old elf are all looking at me with hearts in their eyes. I've accidentally stolen my brother's entire harem, and in the process, I might have just doomed us all. If you are enjoying this novel and want more chapters [BONUS], do these and you will get as much as you want.
