Lol he was blessed by the gods of Yaoi
just wait, they might appear and be attracted to him too.
He's the reincarnation of Princess Yagami, Daikoku was in love with her a looong time ago. They explained this in chapter 10, I think.
Didn't he save each one when they were in their animal forms?
Watch "The World God Only Knows". That should give you an idea why a harem lead is loved. It made me understood that you can make hate into love if you look at it from another perspective
This is something I question in every harem (yes I even consider an all male group going after a person a harem, since I classify harem as many for one.), How come everyone is in love with the lead? I have no qualms about the lead here. He is funny as sin. I just want know why? Also how did he get exposed to so many holy people, was his dad a priest?
