The paramount existences among daemons are known as ‘Great Sages’.

A young man leaves the mountain village and wanders the world, entering the legends step by step, becoming a part of mythology itself.

After a night, surprisingly I acquired a husband!

The purpose of our alliance: Make my husband interested in women!

Frankly speaking, a man who isn’t interested in a woman … is he gay? Having a husband who is suspected to be a gay, I will fight for him and not let him go astray.

So I raise my eyebrows and with a wicked smile: My dear husband, wait and see how I am going to teach you to be a real man!
