This started out great, and was pretty interesting with the action and the main characters. Plenty of interesting plot avenues and the like. Boy is born, gets sick, gets enchanted by a painting and loses his mind for a bit, then becomes strong and overcomes troubles with his family until he strikes out on his own. Then the girls come, and at first it was a love triangle, which was kind of annoying but fine, and didn't interfere that much with the plot. But then everyone confesses, he doesn't really give them an answer, and more girls appear and confess. And that's all women are; annoying as fuck villains, love interests, or his mom. Even when one girl is really strong, she's basically devoting her life to him, and in the end, despite the interesting plot, his growing harem annoys me, so I'll be dropping it here. If you like harems, but aren't bothered by lack of immediate romance, then by all means, give this a read, you'll love it!
